The A/D conversion time per bit is defined as T
A/D conversion requires 9.5 T
The source of the A/D conversion clock is software
selected. The four possible options for T

The ADCON1 and TRIS Registers control the opera-
tion 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
CHS<2:0> bits and the TRIS bits.
