Port A–C High Drive Enable Subregisters
The Port A–C High Drive Enable Subregister (Table 25) is accessed through the Port A–C
Control Register by writing 04H to the Port A–C Address Register. Setting the bits in the
Port A–C High Drive Enable subregisters to 1 configures the specified port pins for high-
current output drive operation. The Port A–C High Drive Enable Subregister affects the
pins directly and, as a result, alternate functions are also affected.
