Port A–C Pull-up Enable Subregisters
The Port A–C Pull-up Enable Subregister (Table 27) is accessed through the Port A–C
Control Register by writing 06H to the Port A–C Address Register. Setting the bits in the
Port A–C Pull-up Enable subregisters enables a weak internal resistive pull-up on the
specified Port pins.
