Transmitter ready-to-send. Controls negation of URTSn to automatically terminate a message transmission.
Attempting to program a receiver and transmitter in the same UART for URTSn control is not permitted and disables
URTSn control for both.
0 The transmitter has no effect on URTSn.
1 In applications where the transmitter is disabled after transmission completes, setting this bit automatically clears
Transmitter clear-to-send. If TXCTS and TXRTS are set, TXCTS controls the operation of the transmitter.
0 UCTSn has no effect on the transmitter.
1 Enables clear-to-send operation. The transmitter checks the state of UCTSn each time it is ready to send a
Stop-bit length control. Selects length of stop bit appended to the transmitted character. Stop-bit lengths of 9/16 to
2 bits are programmable for 6–8 bit characters. Lengths of 1-1/16 to 2 bits are programmable for 5-bit characters. In
all cases, the receiver checks only for a high condition at the center of the first stop-bit position, one bit time after the
last data bit or after the parity bit, if parity is enabled. If an external 1x clock is used for the transmitter, clearing bit 3
selects one stop bit and setting bit 3 selects two stop bits for transmission.
UOP[RTS] one bit time after any characters in the transmitter shift and holding registers are completely sent,
including the programmed number of stop bits.
character. If UCTSn is asserted, the character is sent; if it is deasserted, the signal UTXDn remains in the high
state and transmission is delayed until UCTSn is asserted. Changes in UCTSn as a character is being sent do
not affect its transmission.
