Port A–D Pull-up Enable Subregisters
The Port A–D pull-up enable subregister is accessed through the Port A–D control register
by writing
A–D pull-up enable subregisters, enables a weak internal resistive pull-up on the specified
port pins.
PPUE[7:0]—Port pull-up enabled
0 = The weak pull-up on the port pin is disabled.
1 = The weak pull-up on the port pin is enabled.
Port A–D Alternate Function Set 1 Subregisters
The Port A–D Alternate function set1 subregister is accessed through the Port A–D
control register by writing
Alternate function set 1 subregisters select the Alternate function available at a port pin.
Alternate functions selected by setting or clearing bits of this register are defined in
Alternate Functions
Alternate function selection on port pins must also be enabled as described in
Alternate Function Subregisters
PAFS1[7:0]—Port Alternate function set 1
0 = Port Alternate function selected as defined in
section.
1 = Port Alternate function selected as defined in
section.
