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

This read/write bit determines whether the ESCI generates and checks for odd parity or even parity

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

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

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