1 = The Port pin is configured as a Stop Mode Recovery source. Any logic transition on
this pin during STOP mode initiates Stop Mode Recovery.
Port A–D Pull-up Enable Sub-Registers
The Port A–D Pull-up Enable sub-register
Control register by writing
Port A–D Pull-up Enable sub-registers 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 Sub-Registers
The Port A–D Alternate Function Set1 sub-register
A–D Control register by writing
Function Set 1 sub-registers selects the alternate function available at a port pin. Alternate
Functions selected by setting or clearing bits of this register are defined in
Functions
Alternate function selection on port pins must also be enabled as described in
