7.8.2 Serial Communications Control Register 1
M68HC11E Family — Rev. 3.2
MOTOROLA
Address:
The SCCR1 register provides the control bits that determine word length
and select the method used for the wakeup feature.
R8 — Receive Data Bit 8
T8 — Transmit Data Bit 8
Bit 5 — Unimplemented
M — Mode Bit (select character format)
WAKE — Wakeup by Address Mark/Idle Bit
Bits [2:0] — Unimplemented

Read:
Write:
If M bit is set, R8 stores the ninth bit in the receive data character.
If M bit is set, T8 stores the ninth bit in the transmit data character.
Always reads 0
Always read 0
1 = Start bit, 8 data bits, 1 stop bit
1 = Start bit, 9 data bits, 1 stop bit
0 = Wakeup by IDLE line recognition
1 = Wakeup by address mark (most significant data bit set)
I = Indeterminate after reset
