0 = The drains are enabled for any output mode (unless overridden by the alternate function).
1 = The drain of the associated pin is disabled (OPEN-DRAIN mode).
Port A–D High Drive Enable Subregisters
The Port A–D high drive enable subregister is accessed through the Port
A–D control register by writing
Setting the bits in the Port A–D high drive enable subregisters to 1 configures, the
specified port pins for high output current drive operation. The Port A–D high drive
enable subregister affects the pins directly and, as a result, alternate functions are also
affected.
PHDE[7:0]—Port high drive enabled
0 = The port pin is configured for standard output current drive.
1 = The port pin is configured for high output current drive.
Port A–D Stop Mode Recovery Source Enable Subregisters
The Port A–D Stop Mode Recovery source enable subregister is accessed through the Port
A–D control register by writing
Setting the bits in the Port A–D Stop Mode Recovery source enable subregisters to1,
configures the specified port pins as a Stop Mode Recovery source. During STOP mode,
any logic transition on a port pin enabled as a Stop Mode Recovery source initiates Stop
Mode Recovery.
