NOTE:
The generic names of the IRSCI I/O pins are:
IRSCI I/O (input/output) lines are implemented by sharing parallel I/O
port pins. The full name of an IRSCI input or output reflects the name of
the shared port pin.
names of the IRSCI I/O pins. The generic pin names appear in the text
of this section.
When the IRSCI is enabled, the SCTxD pin is an open-drain output and
requires a pullup resistor to be connected for proper SCI operation.\
The IRSCI consists of a serial communications interface (SCI) and a
infrared interface sub-module as shown in
The SCI module provides serial data transmission and reception, with a
programmable baud rate clock based on the bus clock or the CGMXCLK.
