Enhanced Universal Serial Communication Interface (eUSCI)
The eUSCI modules are used for serial data communication. The eUSCI module supports synchronous
communication protocols such as SPI (3 or 4 pin) and I
2
C, and asynchronous communication protocols such as
UART, enhanced UART with automatic baudrate detection, and IrDA. Each eUSCI module contains two portions,
A and B.
The eUSCI_An module provides support for SPI (3 pin or 4 pin), UART, enhanced UART, or IrDA.
The eUSCI_Bn module provides support for SPI (3 pin or 4 pin) or I2C.
The MSP430FR572x and MSP430FR573x series include one or two eUSCI_An modules (eUSCI_A0,
eUSCI_A1) and one eUSCI_Bn module (eUSCI_B).
TA0, TA1
TA0 and TA1 are 16-bit timers/counters (Timer_A type) with three capture/compare registers each. Each can
support multiple capture/compares, PWM outputs, and interval timing. Each has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
