If the transmitter is reset through a software command, operation stops immediately (see
“UART Command Registers
operation after a disable or software reset.
If the clear-to-send operation is enabled, CTS must be asserted for the character to be transmitted. If CTS
is negated in the middle of a transmission, the character in the shift register is sent and TxD remains in
mark state until CTS is reasserted. If the transmitter is forced to send a continuous low condition by issuing
a
If the transmitter is programmed to automatically negate RTS when a message transmission completes,
RTS must be asserted manually before a message is sent. In applications in which the transmitter is
disabled after transmission is complete and RTS is appropriately programmed, RTS is negated one bit time
after the character in the shift register is completely transmitted. The transmitter must be manually
reenabled by reasserting RTS before the next message is to be sent.
The transmitter must be enabled prior to accepting a
