6.3.12 Pullup Control Register
Read: Anytime, if register is in the map
Write: Anytime, if register is in the map
This register is not in the map in peripheral mode.
These bits select pullup resistors for any pin in the corresponding port that is currently configured as an
input.
PUPH — Pullup Port H Enable Bit
PUPG — Pullup Port G Enable Bit
PUPF — Pullup Port F Enable Bit
PUPE — Pullup Port E Enable Bit
PUPD — Pullup Port D Enable Bit
PUPC — Pullup Port C Enable Bit
PUPB — Pullup Port B Enable Bit
PUPA — Pullup Port A Enable Bit
Freescale Semiconductor
This bit has no effect if port D is being used as part of the data bus (the pullups are inactive).
This bit has no effect if port C is being used as part of the data bus (the pullups are inactive).
This bit has no effect if port B is being used as part of the address bus (the pullups are inactive).
This bit has no effect if port A is being used as part of the address bus (the pullups are inactive).
1 = Enable pullup devices for all port H input pins
0 = Port H pullups disabled
1 = Enable pullup devices for all port G input pins
0 = Port G pullups disabled
1 = Enable pullup devices for all port F input pins
0 = Port F pullups disabled
1 = Enable pullup devices for port E input pins PE3, PE2, and PE0
0 = Port E pullups on PE3, PE2, and PE0 disabled
1 = Enable pullup devices for all port D input pins
0 = Port D pullups disabled
1 = Enable pullup devices for all port C input pins
0 = Port C pullups disabled
1 = Enable pullup devices for all port B input pins
0 = Port B pullups disabled
1 = Enable pullup devices for all port A input pins
0 = Port A pullups disabled
