Ports P, H and J offer pin interrupt capability. The interrupt enable as well as the sensitivity to rising or
falling edges can be individually configured on per-pin basis. All bits/pins in a port share the same interrupt
vector. Interrupts can be used with the pins configured as inputs or outputs.
An interrupt is generated when a bit in the port interrupt flag register and its corresponding port interrupt
enable bit are both set. The pin interrupt feature is also capable to wake up the CPU when it is in STOP or
WAIT mode.
A digital filter on each pin prevents pulses
interrupt. The minimum time varies over process conditions, temperature and voltage
