Description
Port Alternate Function 0 select.
The alternate function 0 function is not selected.
The alternate function 0 function is selected.
Port A–C Output Control Subregisters
The Port A–C Output Control subregisters, shown in Table 20, are accessed through the
Port A–C Control registers by writing 03h to the Port A–C Address registers. Setting the
bits in the Port A–C Output Control subregisters to 1 configures the specified port pins for
open-drain operation. These subregisters affect the pins directly and, as a result, alternate
functions are also affected.
