Universal Serial Communications Interface (USCI)

The USCI module is used for serial data communication. The USCI module supports synchronous

communication protocols such as SPI (3 or 4 pin) and I2C, and asynchronous communication protocols such as

UART, enhanced UART with automatic baudrate detection (LIN), and IrDA. Not all packages support the USCI

functionality.

USCI_A0 provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.

USCI_B0 provides support for SPI (3 or 4 pin) and I2C.

Comparator_A+

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

battery-voltage supervision, and monitoring of external analog signals.

ADC10 (MSP430G2x53 Only)

The ADC10 module supports fast 10-bit analog-to-digital conversions. The module implements a 10-bit SAR

core, sample select control, reference generator, and data transfer controller (DTC) for automatic conversion

result handling, allowing ADC samples to be converted and stored without any CPU intervention.
