Configuring Analog Port Pins
The ADCON1 and TRIS registers control the operation of the A/D port pins. The port pins that
are desired as analog inputs must have their corresponding TRIS bits set (input). If the TRIS bit
is cleared (output), the digital output level (V
The A/D operation is independent of the state of the CHS2:CHS0 bits and the TRIS bits.
Note 1: When reading the port register, any pin configured as an analog input channel will
