Port A Interrupt Flag — PTAIF indicates when a port A interrupt is detected. Writes have no effect on PTAIF.
0 No port A interrupt detected.
1 Port A interrupt detected.
Port A Interrupt Acknowledge — Writing a 1 to PTAACK is part of the flag clearing mechanism. PTAACK
always reads as 0.
Port A Interrupt Enable — PTAIE determines whether a port A interrupt is requested.
0 Port A interrupt request not enabled.
1 Port A interrupt request enabled.
Port A Detection Mode — PTAMOD (along with the PTAES bits) controls the detection mode of the port A
interrupt pins.
0 Port A pins detect edges only.
1 Port A pins detect both edges and levels.
Port A Interrupt Pin Selects — Each of the PTAPSn bits enable the corresponding port A interrupt pin.
0 Pin not enabled as interrupt.
1 Pin enabled as interrupt.
