P0 (0x80)
This port register can be used as other functions besides general purpose I/O.
P0OEN/P1OEN/P3OEN (0xB1, 0xB2, 0xB4)
P0OEN, P1OEN and P3OEN enable the output of port0, 1 and 3. When each bit is cleared to ‘0’, the
output of the corresponding port is enabled. For example, when 4
of port1.3 is enabled.
