Comparator_B (Link to User's Guide)

The primary function of the Comparator_B module is to support precision slope analog-to-digital conversions,

battery voltage supervision, and monitoring of external analog signals.

ADC10_A (Link to User's Guide)

The ADC10_A module supports fast 10-bit analog-to-digital conversions. The module implements a 10-bit SAR

core, sample select control, reference generator and a conversion result buffer. A window comparator with a

lower and upper limit allows CPU independent result monitoring with three window comparator interrupt flags.

CRC16 (Link to User's Guide)

The CRC16 module produces a signature based on a sequence of entered data values and can be used for data

checking purposes. The CRC16 module signature is based on the CRC-CCITT standard.

REF Voltage Reference (Link to User's Guide)

The reference module (REF) is responsible for generation of all critical reference voltages that can be used by

the various analog peripherals in the device.

LDO and Port U

The integrated 3.3-V power system incorporates an integrated 3.3-V LDO regulator that allows the entire

MSP430 microcontroller to be powered from nominal 5-V LDOI when it is made available for the system.

Alternatively, the power system can supply power only to other components within the system, or it can be

unused altogether. The Port U Pins (PU.0 and PU.1) function as general-purpose high-current I/O pins. These

pins can only be configured together as either both inputs or both outputs. Port U is supplied by the LDOO rail. If

the 3.3-V LDO is not being used in the system (disabled), the LDOO pin can be supplied externally.

Embedded Emulation Module (EEM) (S Version) (Link to User's Guide)

The Embedded Emulation Module (EEM) supports real-time in-system debugging. The S version of the EEM

implemented on all devices has the following features:

• Three hardware triggers or breakpoints on memory access

• One hardware trigger or breakpoint on CPU register write access

• Up to four hardware triggers can be combined to form complex triggers or breakpoints

• One cycle counter

• Clock control on module level
