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
Port A–C Control Register by writing
bits in 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.
PSMRE[7:0]—Port Stop Mode Recovery Source Enabled
0 = The port pin is not configured as a Stop Mode Recovery source. Transitions on
alternate function).
this pin during STOP mode does not initiate Stop Mode Recovery.
