IRQ Sense Control Registers (ISCR16H, ISCR16L, ISCRH, ISCRL)
The ISCR registers select the source that generates an interrupt request at pins
IRQ15
to
IRQ0
or
pins
ExIRQ15
to
ExIRQ2
. Switching between pins
IRQ15
to
IRQ2
and pins
ExIRQ15
to
ExIRQ2
is performed by means of IRQ sense port select register 16 (ISSR16) and the IRQ sense port select
register (ISSR).
