UART (UNICOMM)

The UNICOMM-UART peripheral function provide the following key features:

  • Standard asynchronous communication bits for start, stop, and parity
  • Fully programmable serial interface
    • 5, 6, 7 or 8 data bits
    • Even, odd, stick, or no-parity bit generation and detection
    • 1 or 2 stop bit generation
    • LSB-first or MSB-first data transmit and receive
    • Line-break detection
    • Programmable baud rate generation with oversampling by 16, 8 or 3
  • Support for waking up SYSOSC via an asynchronous fast clock request upon start bit detection when operating in low power modes
  • Support transmit and receive loopback mode operation
  • See Table 8-12 for detail information on supported protocols and features
