M — Character Length
WAKE — Wakeup Bit
This read/write bit determines whether SCI characters are 8 bits long
or 9 bits long. The ninth bit can be used as an extra stop bit, as a
receiver wakeup signal, or as a mark or space parity bit. Reset has no
effect on the M bit.
This read/write bit determines which condition wakes up the SCI: a
logic 1 (address mark) in the MSB position of a received character or
an idle condition of the PD0/RDI pin. Reset has no effect on the
WAKE bit.
1 = 9-bit SCI characters
0 = 8-bit SCI characters
1 = Address mark wakeup
0 = Idle line wakeup
