Setting the bits in the Port A-K high drive enable registers (see
the specified port pins for high current output drive operation. The Port A-K high drive
enable registers affect 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.
The Port A-K alternate function high and low registers (see
page 74) select the alternate functions for the selected pins. To determine the alternate
function associated with each port pin, see
changing alternate functions, it is recommended to use word data mode instructions to
perform simultaneous Writes to the port alternate function high and low registers.
Do not enable alternate function for GPIO port pins which do not have an associ-
ated alternate function. Failure to follow this guideline will result in undefined op-
eration.
