Technical Data

WAKE — Wakeup Condition Bit
ILTY — Idle Line Type Bit
PEN — Parity Enable Bit
PTY — Parity Bit
Freescale Semiconductor, Inc.
This read/write bit determines which condition wakes up the SCI: a
logic 1 (address mark) in the most significant bit position of a received
character or an idle condition on the PE1/RxD pin. Reset clears the
WAKE bit.
This read/write bit determines when the SCI starts counting logic 1s
as idle character bits. The counting begins either after the start bit or
after the stop bit. If the count begins after the start bit, then a string of
logic 1s preceding the stop bit may cause false recognition of an idle
character. Beginning the count after the stop bit avoids false idle
character recognition, but requires properly synchronized
transmissions. Reset clears the ILTY bit.
This read/write bit enables the SCI parity function. See
When enabled, the parity function inserts a parity bit in the most
significant bit position. See
This read/write bit determines whether the SCI generates and checks
for odd parity or even parity. See
