Multiple Serial Interface
Serial Communication Interface (SCI)
RIE — Receiver Interrupt Enable
0 = RDRF and OR interrupts disabled, RAF interrupt in WAIT mode
disabled
1 = SCI interrupt will be requested whenever the RDRF or OR
status flag is set, or when RAF is set while in WAIT mode with
VDDPLL high.
ILIE — Idle Line Interrupt Enable
0 = IDLE interrupts disabled
1 = SCI interrupt will be requested whenever the IDLE status flag
is set.
TE — Transmitter Enable
0 = Transmitter disabled
1 = SCI transmit logic is enabled and the TXD pin (Port S bit 1/bit
3) is dedicated to the transmitter. The TE bit can be used to
queue an idle preamble.
RE — Receiver Enable
0 = Receiver disabled
1 = Enables the SCI receive circuitry.
RWU — Receiver Wake-Up Control
0 = Normal SCI Receiver
1 = Enables the wake-up function and inhibits further receiver
interrupts. Normally hardware wakes the receiver by
automatically clearing this bit.
SBK — Send Break
0 = Break generator off
1 = Generate a break code (at least 10 or 11 contiguous zeros).
As long as SBK remains set the transmitter will send zeros. When
SBK is changed to zero, the current frame of all zeros is finished
before the TxD line goes to the idle state. If SBK is toggled on and off,
the transmitter will send only 10 (or 11) zeros and then revert to mark
idle or sending data.
