XR16V698
2.25V TO 3.6V HIGH PERFORMANCE OCTAL UART WITH 32-BYTE FIFO
MSR[3]: Transmitter Disable
This bit can be used to disable the transmitter by halting the Transmit Shift Register (TSR). When this bit is set
to a ’1’, the bytes already in the FIFO will not be sent out. Also, any more data loaded into the FIFO will stay in
the FIFO and will not be sent out. When this bit is set to a ’0’, the bytes currently in the TX FIFO will be sent
out. Please note that setting this bit to a ’1’ stops any character from going out. Also, this bit must be a ’0’ for
Send Char Immediate function (see MCR[3]).
•
•
Logic 0 = Enable Transmitter (default).
Logic 1 = Disable Transmitter.
