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–C High Drive Enable Sub-Registers
The Port A–C High Drive Enable sub-register
A–C Control register by writing
the Port A–C High Drive Enable sub-registers to 1 configures the specified port pins for
high current output drive operation. The Port A–C High Drive Enable sub-register 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–C Stop Mode Recovery Source Enable Sub-Registers
The Port A–C Stop Mode Recovery Source Enable sub-register
through the Port A–C Control register by writing
Setting the bits in the Port A–C Stop Mode Recovery Source Enable sub-registers to 1
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.
