WAKE — Wakeup Condition Bit
ILTY — Idle Line Type Bit
PEN — Parity Enable Bit
PTY — Parity Bit

This read/write bit determines which condition wakes up the ESCI: a 1 (address mark) in the MSB
position of a received character or an idle condition on the RxD pin. Reset clears the WAKE bit.
This read/write bit determines when the ESCI starts counting 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 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 ESCI parity function (see
function inserts a parity bit in the MSB position (see
This read/write bit determines whether the ESCI generates and checks for odd parity or even parity

Changing the PTY bit in the middle of a transmission or reception can
generate a parity error.
