Enhanced Serial Communications Interface (ESCI) Module
PTY — Parity Bit
13.8.2 ESCI Control Register 2
ESCI control register 2 (SCC2):
SCTIE — ESCI Transmit Interrupt Enable Bit
TCIE — Transmission Complete Interrupt Enable Bit
SCRIE — ESCI Receive Interrupt Enable Bit
138
This read/write bit determines whether the ESCI generates and checks for odd parity or even parity
(see

This read/write bit enables the SCTE bit to generate ESCI transmitter interrupt requests. Setting the
SCTIE bit in SCC2 enables the SCTE bit to generate interrupt requests.
This read/write bit enables the TC bit to generate ESCI transmitter interrupt requests.
This read/write bit enables the SCRF bit to generate ESCI receiver interrupt requests. Setting the
SCRIE bit in SCC2 enables the SCRF bit to generate interrupt requests.
1 = Odd parity
0 = Even parity
1 = SCTE enabled to generate interrupt
0 = SCTE not enabled to generate interrupt
1 = TC enabled to generate interrupt requests
0 = TC not enabled to generate interrupt requests
1 = SCRF enabled to generate interrupt
0 = SCRF not enabled to generate interrupt
Enables these interrupt requests:

Enables the transmitter
Enables the receiver
Enables ESCI wakeup
Transmits ESCI break characters

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