LDD — LED Direct Drive Control
PCP — Port C Pullup Enable
PBP — Port B Pullup Enable
PAP — Port A Pullup Enable
This read/write bit controls the output current capability of port C.
When set, the port C pins have current limiting ability so that a LED
can be connected directly between the port pin and V
without the need of a series resistor.
This read/write bit controls the pullup option for port C[7:0] if its
respective port pin is configured as an input.
This read/write bit controls the pullup option for the eight bits of port B
if its respective port pin is configured as an input.
This read/write bit controls the pullup option for the eight bits of port A
if its respective port pin is configured as an input.
1 = When respective port is configured as an output, make port C
0 = Configure port C to become standard I/O port pins
1 = Configure port C to have internal pullups
0 = Disconnect port C internal pullups
1 = Configure port B to have internal pullups
0 = Disconnect port B internal pullups
1 = Configure port A to have internal pullups
0 = Disconnect port A internal pullups
become current limiting 3 mA source/10 mA sink port pins
