Over-Current Interrupt Enable register port P —
This bit enables or disables the over-current interrupt on PP2.
1 PP2 over-current interrupt enabled
0 PP2 over-current interrupt disabled (interrupt flag masked)
Pin Interrupt Enable register port P —
This bit enables or disables the edge sensitive pin interrupt on the associated pin. An interrupt can be generated if
the pin is operating in input or output mode when in use with the general-purpose or related peripheral function.
1 Interrupt is enabled
0 Interrupt is disabled (interrupt flag masked)
Over-Current Interrupt Flag register port P —
This flag asserts if an over-current condition is detected on PP2
1 PP2 Over-current event occurred
0 No PP2 over-current event occurred
Pin Interrupt Flag register port P —
This flag asserts after a valid active edge was detected on the related pin
a rising or a falling edge based on the state of the polarity select register. An interrupt will occur if the associated
interrupt enable bit is set.
1 Active edge on the associated bit has occurred
0 No active edge occurred
