NOTE:
PTE4P — Pin PTE4 Pullup Enable
When the USB module is enabled, the pullup controlled by PTE4P is
disconnected; PTE4/D– pin functions as D– which has a 1.5kΩ
programmable pull-up resistor. (See
PTE3P — Pin PTE3 Pullup Enable
PCP — Port C Pullup Enable
PAP — Port A Pullup Enable
This read/write bit controls the pullup option for the PTE4 pin when the
pin is configured as an input and the USB module is disabled.
This read/write bit controls the pullup option for the PTE3 pin when the
pin is configured as an input and the USB module is disabled.
This read/write bit controls the pullup option for the PTC1 and PTC0
pins. When set, a pullup device is connected when a pin is configured
as an input.
This read/write bit controls the pullup option for the PTA7–PTA0 pins.
When set, a pullup device is connected when a pin is configured as
an input.
1 = PTD1 and PTD0 configured for infrared LED drive capability;
0 = PTD1 and PTD0 configured as standard open-drain I/O port
1 = Configure PTE4 to have internal pullup
0 = Disconnect PTE4 internal pullup
1 = Configure PTE3 to have internal pullup
0 = Disconnect PTE3 internal pullup
1 = Configure port C to have internal pullups
0 = Disconnect port C internal pullups
1 = Configure port A to have internal pullups
0 = Disconnect port A internal pullups
when a pin is set as an output, the pin is an open-drain pin with
25mA current sink capability
