A value of 0 sets the direction to input; 1 sets the direction to output IRQ enable/disable for each input port. Setting a bit to 1 enables interrupts for the corresponding port. Edge detection for each input port. Specifies which bit of the output port to set. Specifies which output bit to clear. 2 interruptmask (1) R/W 3 edge capture (1), (2) 4 4 outset RAW W W 5 outclear
