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 pullup resistor. (See
PTE3P — Pin PTE3 Pullup Enable
PCP — Port C Pullup Enable
PBP — Port B 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 PTC7–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 PTB7–PTB0 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 = Configure PTE4 to have internal pullup to V
0 = Disconnect PTE4 internal pullup
1 = Configure PTE3 to have internal pullup to V
0 = Disconnect PTE3 internal pullup
1 = Configure port C to have internal pullups to V
0 = Disconnect port C internal pullups
1 = Configure port B to have internal pullups to V
0 = Disconnect port B internal pullups
1 = Configure port A to have internal pullups to V
0 = Disconnect port A internal pullups
