MAKE_IRQ0/MAKE_IRQ1 (9500h/9501h)
The MAKE_IRQ registers specify if an interrupt should be generated after the related I/O input has changed.
The I/O pin, which caused the interrupt, will be indicated in the STATUS0/STATUS1 flag registers.
IOx:
0:
no interrupt on signal change
1:
generate an interrupt on signal change

The OUT_MUX registers specify the source signal for each of the I/O outputs. Every 2 bits are used as select
signals for the 4-way output multiplexer of the designated I/O.
