Note 1:
Writes to PORTx are actually written to the corresponding LATx register. Reads from LATx register return
register values, not I/O pin values.

. Digital Input buffer disabled.
0
= Digital I/O. Pin is assigned to port or Digital special function.
Note 1:
Setting a pin to an analog input automatically disables the digital input circuitry. Weak pull-ups, if
available, are unaffected. The corresponding TRIS bit must be set to Input mode by the user in order to
allow external control of the voltage on the pin.
