PT1AD0
Port AD0 general purpose input/output data—Data Register, ATD AN analog input
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.

Port AD0 data direction—
This bit determines whether the associated pin is an input or output.
To use the digital input function the ATD Digital Input Enable Register (ATD0DIEN) has to be set to logic level “1”.
1 Associated pin configured as output
