6. Input and Output port A

The EM6580 has:

- port PA[3:0], one 4-bit input/output port

- port PA[4], one 1 bit input port.

- port PA[5], one 1 bit input/output. (not available in 8-pin package).

Pull-up and Pull-down resistors can be added to all these ports with register options.

Refer to RegMFP1 table chapter 14.8

As shown in Figure 10, Logic for the Wake up on change reset which is possible only from Sleep mode,

Debouce and IRQ function on Rising or falling edge are implemented only twice but can be attached and

configured by registers to 4 different pads when used as inputs.

Ports PA[0] and PA[5] can be configured to have wakeup on Change, and debounced or non-debounced IRQ

on the falling or rising edge. The same function is available on ports PA[3] or PA[4] which in addition can be

dedicated to input reset . Registers RegPACntl1 and RegPACntl2 make this selection.
