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

SCTE bit to generate transmitter interrupt requests
TC bit to generate transmitter interrupt requests
SCRF bit to generate receiver interrupt requests
IDLE bit to generate receiver interrupt requests

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