These bits select pull-up resistors for any pin in the corresponding port that is currently configured as
an input. This register is not in the map in peripheral mode.
Read and write anytime.
PUPE — Pull-Up Port E Enable
Pin PE1 always has a pull-up. Pins PE6, PE5, and PE4 never have pull-ups.
0 = Port E pull-ups on PE7, PE3, PE2, and PE0 are disabled.
1 = Enable pull-up devices for port E input pins PE7, PE3, PE2, and PE0.
PUPB — Pull-Up Port B Enable
0 = Port B pull-ups are disabled.
1 = Enable pull-up devices for all port B input pins.
This bit has no effect if port B is being used as part of the address/data bus (the pull-ups are inactive).
PUPA — Pull-Up Port A Enable
0 = Port A pull-ups are disabled.
1 = Enable pull-up devices for all port A input pins.
This bit has no effect if port A is being used as part of the address/data bus (the pull-ups are inactive).
These bits select reduced drive for the associated port pins. This gives reduced power consumption and
reduced RFI with a slight increase in transition time (depending on loading). The reduced drive function
is independent of which function is being used on a particular port. This register is not in the map in
peripheral mode.
Normal: write once; Special: write anytime except the first time. Read anytime.
RDPE — Reduced Drive of Port E
0 = All port E output pins have full drive enabled.
1 = All port E output pins have reduced drive capability.
RDPB — Reduced Drive of Port B
0 = All port B output pins have full drive enabled.
1 = All port B output pins have reduced drive capability.
RDPA — Reduced Drive of Port A
0 = All port A output pins have full drive enabled.
1 = All port A output pins have reduced drive capability.
