8 BLUETOOTH SOFTWARE STACKS WRAP THOR 2022-1 is supplied with Bluetooth stack firmware which runs on the internal RISC microcontroller. This is compliant with the Bluetooth specification v1.1. The WRAP THOR 2022-1 software architecture allows Bluetooth processing overheads to be shared in different ways between the internal RISC microcontroller and the host processor. The upper layers of the Bluetooth stack (above HCI) can be run either on-chip or on the host processor.
In this version of the firmware the upper layers of the Bluetooth stack up to RFCOMM are run onchip. This reduces host-side software and hardware requirements at the expense of some of the power and flexibility of the HCI only stack. 8.2 VIRTUAL MACHINE STACK Figure 5: Virtual Machine This version of the stack firmware requires no host processor.
9 UART INTERFACE WRAP THOR 2022-1 Universal Asynchronous Receiver Transmitter (UART) interface provides a simple mechanism for communicating with other serial devices using the RS232 standard (1). WRAP THOR 2022-1 Figure 6: Universal Asynchronous Receiver Four signals are used to implement the UART function, as shown in Figure 5. When WRAP THOR 2022-1 is connected to another digital device, UART_RX and UART_TX transfer data between the two devices.
The UART interface is capable of resetting WRAP THOR 2022-1 upon reception of a break signal. A Break is identified by a continuous logic low on the UART_RX terminal, as shown in figure 9.16. If tBRK is longer than the value, defined by the Persistent Store Key PSKEY_HOST_IO_UART_RESET_TIMEOUT, (0x1a4), a reset will occur. This feature allows a host to initialise the system to a known state. Also, WRAP THOR 2022-1 can emit a Break character that may be used to wake the Host.
10 USB INTERFACE WRAP THOR 2022-1 USB devices contain a full-speed (12Mbits/s) USB interface, capable of driving a USB cable directly. No external USB transceiver is required. The device operates as a USB peripheral, responding to requests from a master host controller such as a PC. Both the OHCI and the UHCI standards are supported. The set of USB endpoints implemented behave as specified in the USB section of the Bluetooth specification v1.1 and v1.2 part H2.
WRAP THOR 2022-1 Figure 8: Connections to WRAP THOR 2022-1 for Self-Powered Mode The terminal marked USB_ON can be any free PIO pin. The PIO pin selected must be registered by setting PSKEY_USB_PIO_VBUS (0x2d1) to the corresponding pin number. 10.5 BUS-POWERED MODE In bus-powered mode the application circuit draws its current from the 5V VBUS supply on the USB cable. WRAP THOR 2022-1 negotiates with the PC during the USB enumeration stage about power consumption.
USB specification. This is not normally a problem with modern regulators. Ensure that external LEDs and/or amplifiers can be turned off by WRAP THOR 2022-1. The entire circuit must be able to enter the suspend mode.

10.7 DETACH AND WAKE_UP SIGNALLING WRAP THOR 2022-1 can provide out-of-band signalling to a host controller by using the dedicated control lines called ‘USB_DETACH’ and ‘USB_WAKE_UP’. These are outside the USB specification (no wires exist for them inside the USB cable), but can be useful when embedding WRAP THOR 2022-1 into a circuit where no external USB is visible to the user.
11 SERIAL PERIPHERAL INTERFACE WRAP THOR 2022-1 uses 16-bit data and 16-bit address during serial peripheral interface transactions. Such transactions will occur whether the internal processor is running or is stopped. This section details the considerations required when interfacing to WRAP THOR 2022-1 via the four dedicated serial peripheral interface terminals. Data may be written or read one word at a time or the auto-increment feature may be used to access blocks. 11.

11.6 READING FROM WRAP THOR 2022-1 Reading from WRAP THOR 2022-1 is similar to writing to it. An 8-bit read command (00000011) is sent first, followed by the address of the location to be read. WRAP THOR 2022-1 then outputs the 16-bit contents of the location on MISO with a check-word during T[15:0] and data during bits D[15:0]. The check-word is composed of {command, address [15:8]}. The check-word may be used to confirm a read operation to a memory location.
12 PCM Pulse Code Modulation (PCM) is the standard method used to digitise human voice patterns for transmission over digital communication channels. Through its PCM interface, WRAP THOR 2022-1 has hardware support for continual transmission and reception of PCM data, thus reducing processor overhead for wireless headset applications. WRAP THOR 2022-1 offers a bi-directional digital audio interface that routes directly into the baseband layer of the on-chip firmware.
WRAP THOR 2022-1 Figure 16: WRAP THOR 2022-1 as PCM Interface Master When configured as the Slave of the PCM interface, WRAP THOR 2022-1 accepts PCM_CLK rates up to 2048kHz. WRAP THOR 2022-1 Figure 17: WRAP THOR 2022-1 as PCM Interface Slave Bluegiga Proprietary 26 Version 1.
Note: A minimum of 3 clock cycles needs to be applied before a SCO is established Long Frame Sync Long Frame Sync is the name given to a clocking format that controls the transfer of PCM data words or samples. In Long Frame Sync, the rising edge of PCM_SYNC indicates the start of the PCM word. When WRAP THOR 2022-1 is configured as PCM Master, generating PCM_SYNC and PCM_CLK, then PCM_SYNC is 8-bits long.
As with Long Frame Sync, WRAP THOR 2022-1 samples PCM_IN on the falling edge of PCM_CLK and transmits PCM_OUT on the rising edge. PCM_OUT may be configured to be high impedance on the falling edge of PCM_CLK in the LSB position or on the rising edge. 12.3 MULTI-SLOT OPERATION More than one SCO connection over the PCM interface is supported using multiple slots. Up to three SCO connections can be carried over any of the first four slots.
The start of frame is indicated by PCM_SYNC and runs at 8kHz. With WRAP THOR 2022-1 in Slave mode, the frequency of PCM_CLK can be up to 4.096MHz. In order to configure the PCM interface to work in GCI mode it is necessary to set GCI_MODE bit in PSKEY_PCM_CONFIG32. The SAMPLE_FORMAT bits should be set to 0x0b01 to allow for the double clocking of each. 12.5 SLOTS AND SAMPLE FORMATS WRAP THOR 2022-1 can receive and transmit on any selection of the first four slots following each sync pulse.
12.6 ADDITIONAL FEATURES WRAP THOR 2022-1 has a mute facility that forces PCM_OUT to be 0. In Master mode, PCM_SYNC may also be forced to 0 while keeping PCM_CLK running (which some CODECS use to control power-down). 12.7 PCM TIMING INFORMATION PCM Master Timing Note: (1) Assumes normal system clock operation. Figures will vary during low power modes, when system clock speeds are reduced. (2) Valid for temperatures between -40°C and +105°C Bluegiga Proprietary 30 Version 1.

13 PIO The Parallel Input Output (PIO) Port is a general-purpose I/O interface to WRAP THOR 2022-1. The port consists of six programmable, bi-directional I/O lines, PIO[2:7]. Programmable I/O lines can be accessed either via an embedded application running on WRAP THOR 2022-1 or via private channel or manufacturer-specific HCI commands. PIO[2]/USB_PULL_UP (1) This is a multifunction terminal. The function depends on whether WRAP THOR 2022-1 is a USB or UART capable version.
