PIOINT
PIO Interrupt
A PIOINT bit is set when its corresponding PIO
pin changes Value and the edge for that pin is
enabled via the PIORMASK or PIOFMASK
register. The pin must be set as an input in the
PIODIR register to generate an interrupt.
Read
0: No change detected.
1: Change detected.
Write
All bits are cleared by writing 1 to either this
register or the PIOEDGE register.
NOTE: Changes to the PIO pins can only be
detected when the clock is running.
