270 Multiple Serial Interface Freescale Semiconductor
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.
PE — Parity Enable
0 = Parity is disabled.
1 = Parity is enabled.
PT — Parity Type
If parity is enabled, this bit determines even or odd parity for both the
receiver and the transmitter.
0 = Even parity is selected. An even number of ones in the data
character causes the parity bit to be zero and an odd number
of ones causes the parity bit to be one.
1 = Odd parity is selected. An odd number of ones in the data
character causes the parity bit to be zero and an even number
of ones causes the parity bit to be one.
Read or write anytime.
TIE — Transmit Interrupt Enable
0 = TDRE interrupts disabled
1 = SCI interrupt will be requested whenever the TDRE status flag
is set.
TCIE — Transmit Complete Interrupt Enable
0 = TC interrupts disabled
1 = SCI interrupt will be requested whenever the TC status flag is
set.
