About the Embedded Module C H A P T E R 1 Overview Digi Connect Wi-EM 9210 Overview The embedded modules are part of the Digi Connect family of device servers that provide simple, reliable and cost-effective network connections for serial devices.
Types of Modules Cautions To guard against damage to the module due to electrostatic discharge (ESD), do not remove it from its protective packaging until you have been properly grounded. To ground yourself, put the wrist strap on (included in the package) and then attach the clip to a metal surface. Input voltage for the module is 3.3 VDC.

Programming Considerations C H A P T E R 3 This chapter addresses the embedded modules programming considerations. Note: This chapter applies only to development kit customers. GPIO General Information The Wi-EM 9210 processor supports 16 general purpose I/O (GPIO) lines, some of which are reserved for specific functions and some of which can be customized.
GPIO GPIO Registers Six registers govern the 16 GPIO pins. There are four configuration registers. Each has eight bits dedicated to the configuration of each GPIO. .
Programming Considerations GPIO Configuration Setings using bits D07:00 D02 DIR Controls the pin direction when the FUNC field is configured for GPIO mode, function #3. 0 Input 1 Output All GPIO pins reset to the input state. Note: The pin direction is controlled by the selected function in modes #0 through #2. D01 INV Controls the inversion function of the GPIO pin. 0 Disables the inversion function 1 Enables the inversion function This bit applies to all functional modes.
GPIO GPIO [15:0] Control Register There is one GPIO control Register that governs all 16 GPIO pins. When a GPIO pin is configured as a GPIO output, the corresponding bit in the GPIO Control Register is driven out the GPIO pin. In all configurations, the CPU has read/write access to these registers. Register bits D31:16 are unused GPIO pins. These pins are being used as memory data bits 15:00.
Programming Considerations GPIO pin use table GPIO Pin Use Name TXSD/ SPI_TX/ GPIO-6 DTR/GPIO5 RTS/ SPI_CLK/ GPIO-4 (See description) RXD/ SPI_RX/ GPIO-7 DSR/GPIO3 Register Bit GPIO[7] GPIO[6] GPIO[5]or GPIO[4] GPIO[3] GPIO[2] External Interface Description Allocated Pin 4 on the main header Used for the serial TXD or SPI_TX, but could be reassigned as a GPIO, timer out 7 or in 8. If used with the development board, this pin maps to GPIO-6.
GPIO GPIO Pin Use Name CTS/GPIO2 DCD// SPI_EN/ GPIO-1 TXD2/ GPIO-8 GPIO[1] GPIO[0] GPIO[15] Category External Interface Allocated Pin 7 on the main header Used for the serial CTS, but could be reassigned as a GPIO, IRQ0 or PICO-1. If used with the development board, this pin maps to GPIO-2. Allocated Pin 8 on the main header Used for the serial DCD or SPI_EN, but could be reassugned as a GPIO or PICO-0. If used with the development board, this pin maps to GPIO-1.
Programming Considerations GPIO Pin Use Name Register Bit Category External Interface Description MFGI GPIO[9] Reserved N/A N/A Red LED GPIO[8] Allocated Connected to the Red LED Used for diagnostics and power on indication. Note: The Wi-EM 9210 signals PIC0-[0:3] provided by the programmable FIMs (DRPIC) are only applicable when running NET+OS.
Embedded Module Reset Embedded Module Reset Hard Reset The embedded modules support a hardware reset on pin 10 of the 12-pin header. The unit will be forced into a hard reset if this pin is pulled low. When used with the development board, this pin is wired to reset button SW5, which means it acts as a hard reset button. The JTAG version of the Wi-EM 9210 EM module has a 3-pin jumper (JP1) to allow two modes of operation. Shorted 1-2: The CPU and other registers are reset.
Programming Considerations SDRAM The Wi-EM 9210 module has 16 MB of SDRAM memory, controlled by chip select 1 (default = dy_cs0), located at 0x00000000.
