13.11.8 SCI Infrared Control Register
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
Address:
Infrared Serial Communications Interface Module (IRSCI)
The infrared control register contains the control bits for the infrared sub-
module.
TNP1 and TNP0 — Transmitter Narrow Pulse Bits
IREN — Infrared Enable Bit

•
These read/write bits select the infrared transmitter narrow pulse
width as shown in
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
