Overview
The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a highly flexible serial
communication device.
The PRUSART0 bit in ”PRR – Power Reduction Register” on page 42 must be written to zero to enable USART0
module.
A simplified block diagram of the USART Transmitter is shown in Figure 20-1 on page 152. CPU accessible I/O
Registers and I/O pins are shown in bold.
