4.7. Communications Peripherals
4.7.1. USART (USART0)
The USART uses two signals (TX and RX) to communicate serially with an external device. In addition to these
signals, the USART module can optionally use a clock (UCLK) or hardware handshaking (RTS and CTS).
The USART module provides the following features:
4.7.2. UART (UART0)
The low-power UART uses two signals (TX and RX) to communicate serially with an external device.
The UART0 module can operate in PM8 mode by taking the clock directly from the RTC0 time clock (RTC0TCLK)
and running from the low power mode charge pump. This will allow the system to conserve power while
transmitting or receiving UART traffic. The UART supports standard baud-rates of 9600, 4800, 2400 and 1200 in
this low power mode.
The UART0 module provides the following features:
