12.9.8 IRSCI Infrared Control Register
The infrared control register contains the control bits for the infrared sub-module.
TNP1 and TNP0 — Transmitter Narrow Pulse Bits
IREN — Infrared Enable Bit
Freescale Semiconductor

•
These read/write bits select the infrared transmitter narrow pulse width as shown in
clears TNP1 and TNP0.
This read/write bit enables the infrared sub-module for encoding and decoding the SCI data stream.
When this bit is clear, the infrared sub-module is disabled. Reset clears the IREN bit.
1 = infrared sub-module enabled
0 = infrared sub-module disabled
Enables the infrared sub-module
Selects the infrared transmitter narrow pulse width
