Bus Control and Input/Output
PUPJ — Pull-Up or Pull-Down Port J Enable
0 = Port J resistive loads (pull-ups or pull-downs) are disabled.
1 = Enable resistive load devices (pull-ups or pull-downs) for all
port J input pins.
PUPH — Pull-Up or Pull-Down Port H Enable
0 = Port H resistive loads (pull-ups or pull-downs) are disabled.
1 = Enable resistive load devices (pull-ups or pull-downs) for all
port H input pins.
PUPE — Pull-Up Port E Enable
0 = Port E pull-ups on PE7, PE3, PE2, PE1 and PE0 are disabled.
1 = Enable pull-up devices for port E input pins PE7, PE3, PE2,
PE1 and PE0.
When this bit is set port E input pins 7, 3, 2, 1 & 0 have an active pull-
up device.
PUPB — Pull-Up Port B Enable
0 = Port B pull-ups are disabled.
1 = Enable pull-up devices for all port B input pins.
PUPA — Pull-Up Port A Enable
0 = Port A pull-ups are disabled.
1 = Enable pull-up devices for all port A input pins.
