17.8 Cautions

(1) When the clock supply to UARTCn is stopped (for example, in IDLE1, IDLE2, or STOP mode), the operation
(2) Start up the UARTCn in the following sequence.
(3) Stop the UARTCn in the following sequence.
(4) In transmit mode (UCnCTL0.UCnPWR bit = 1 and UCnCTL0.UCnTXE bit = 1), do not overwrite the same
(5) In continuous transmission, the communication rate from the stop bit to the next start bit is extended 2 base
<1> Set the UCnCTL0.UCnPWR bit to 1.
<2> Set the ports.
<3> Set the UCnCTL0.UCnTXE bit to 1, UCnCTL0.UCnRXE bit to 1.
<1> Set the UCnCTL0.UCnTXE bit to 0, UCnCTL0.UCnRXE bit to 0.
<2> Set the ports and set the UCnCTL0.UCnPWR bit to 0 (it is not a problem if port setting is not changed).
value to the UCnTX register by software because transmission starts by writing to this register. To transmit the
same value continuously, overwrite the same value.
clocks more than usual. However, the reception side initializes the timing by detecting the start bit, so the
reception result is not affected.
Remark
stops with each register retaining the value it had immediately before the clock supply was stopped. The
TXDCn pin output also holds and outputs the value it had immediately before the clock supply was stopped.
However, the operation is not guaranteed after the clock supply is resumed. Therefore, after the clock supply
is resumed, the circuits should be initialized by setting the UCnCTL0.UCnPWR, UCnCTL0.UCnRXEn, and
UCnCTL0.UCnTXEn bits to 000.
