Initial Value Function
00h
Outgoing data. Read returns the value of PAD.
00h
Selects the direction of each IO pin.
00h
Masks each interrupt source:
0 = disable interrupt (default)
1 = enable interrupt
00h
Current interrupt request status (read only):
0 = no interrupt request
1 = interrupt pending (masked interrupt is always 0)
