Port P interrupt enable—
This bit enables or disables on the edge sensitive pin interrupt on the associated pin.
1 Interrupt is enabled
0 Interrupt is disabled (interrupt flag masked)
Port P interrupt flag—
The flag bit is set after an active edge was applied to the associated input pin. This can be a rising or a falling edge
based on the state of the polarity select register.
Writing a logic “1” to the corresponding bit field clears the flag.
1 Active edge on the associated bit has occurred (an interrupt will occur if the associated enable bit is set)
0 No active edge occurred
