Universal Serial Communication Interfaces (USCI_A0, USCI_B0, USCI_A1, USCI_B1)
The universal serial communication interface (USCI) module is used for serial data communication. The USCI
module supports synchronous communication protocols like SPI (3 or 4 pin), I2C and asynchronous
communication protocols like UART, enhanced UART with automatic baudrate detection (LIN), and IrDA.
USCI_A0 and USCI_A1 provides support for SPI (3 or 4 pin), UART, enhanced UART and IrDA.
USCI_B0 and USCI_B1 provides support for SPI (3 or 4 pin) and I2C.
timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
