MC68HC11A8TS/D
RESET:
RESET:
Set if transmit data can be written to SCDR; if TDRE is zero, transmit data register is busy. Cleared by
SCSR read with TDRE set followed by SCDR write.
Set if transmitter is idle (no data, preamble, or break transmission in progress). Cleared by SCSR read
with TC set followed by SCDR write.
0 = Wake up by IDLE line recognition
1 = Wake up by address mark (most significant data bit set)
0 = TDRE interrupts disabled
1 = SCI interrupt requested when TDRE status flag is set
0 = TC interrupts disabled
1 = SCI interrupt requested if TC is set to one
0 = RDRF and OR interrupts disabled
1 = SCI interrupt requested when RDRF flag or the OR status flag is set
0 = IDLE interrupts disabled
1 = SCI interrupt requested when IDLE status flag is set
0 = Transmitter disabled
1 = Transmitter enabled
0 = Receiver disabled
1 = Receiver enabled
0 = Normal SCI receiver
1 = Wake up enabled and receiver interrupts inhibited
0 = Break generator off
1 = Break codes generated as long as SBK is set to one
