IRTX
The general-purpose I/O signals for the L64118 let you control and
monitor various external events. These signals consist of eight groups.
Group 7 contains dedicated GPIO signals, whereas the other groups
multiplex the GPIO signals with other functions. Note that all pins within
a GPIO group must be enabled or disabled as a group; however,
individual GPIO pins can be configured as inputs or outputs using the
General-Purpose Control register. The GPIO groups and associated pins
are listed in Table 5 through Table 12.

Group 1: EBus Signals
Infrared Transmitter
This signal serves as the infrared transmitter output.
GPIO44
IRRX1 can serve as a general-purpose I/O signal
(GPIO44) by setting bit 7 in the General-Purpose Mode
register.
By default, this signal floats after reset.
