PE — Parity Enable
PT — Parity Type
Read or write anytime.
TIE — Transmit Interrupt Enable
TCIE — Transmit Complete Interrupt Enable
In the long mode, the SCI circuitry does not begin counting ones in the
search for the idle line condition until a stop bit is received. Therefore,
the last byte’s stop bit and preceding “1” bits do not affect how quickly
an idle line condition can be detected.
If parity is enabled, this bit determines even or odd parity for both the
receiver and the transmitter.
0 = Parity is disabled.
1 = Parity is enabled.
0 = Even parity is selected. An even number of ones in the data
1 = Odd parity is selected. An odd number of ones in the data
0 = TDRE interrupts disabled
1 = SCI interrupt will be requested whenever the TDRE status flag
0 = TC interrupts disabled
1 = SCI interrupt will be requested whenever the TC status flag is
