6.8.4 Timer32
Timer32 is an ARM dual 32-bit timer module. It contains two 32-bit timers, each of which can be
configured as two independent 16-bit timers. The two timers can generate independent events or a
combined event, which can be processed according to application requirements.
6.8.5 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-pin or 4-pin) and I²C, and asynchronous communication
protocols such as UART, enhanced UART with automatic baudrate detection, and IrDA.
The eUSCI_An module provides support for SPI (3-pin or 4-pin), UART, enhanced UART, and IrDA.
The eUSCI_Bn module provides support for SPI (3-pin or 4-pin) and I²C.
The MSP432P401x devices offer up to four eUSCI_A and four eUSCI_B modules.
6.8.6 Real-Time Clock (RTC_C)
The RTC_C module contains an integrated real-time clock. It integrates an internal calendar which
compensates for months with less than 31 days and includes leap year correction. The RTC_C also
supports flexible alarm functions, offset-calibration and temperature compensation. The RTC_C operation
is available in LPM3 and LPM3.5 modes to minimize power consumption.
