Field LOOP writer - Selects data loopback mode.

Implementations

impl<'a, const O: u8> LOOP_W<'a, O>

pub fn normal(self) -> &'a mut W

Normal operation.

pub fn loopback(self) -> &'a mut W

Loopback mode. This provides a mechanism to perform diagnostic loopback testing for USART data. Serial data from the transmitter (Un_TXD) is connected internally to serial input of the receive (Un_RXD). Un_TXD and Un_RTS activity will also appear on external pins if these functions are configured to appear on device pins. The receiver RTS signal is also looped back to CTS and performs flow control if enabled by CTSEN.
