17.2
The A/D conversion time per bit is defined as T
A/D conversion requires 12 T
The source of the A/D conversion clock is software
selectable. There are seven possible options for T
• 2T
• 4T
• 8T
• 16T
• 32T
• 64T
• Internal RC oscillator
For correct A/D conversions, the A/D conversion clock
(T
of 1.6 s.
Table 17-1 shows the resultant T

The ADCON1, TRISA, TRISF and TRISH registers
control the operation of the A/D port pins. The port pins
needed as analog inputs must have their correspond-
ing TRIS bits set (input). If the TRIS bit is cleared (out-
put), the digital output level (V
converted.
The A/D operation is independent of the state of the
CHS3:CHS0 bits and the TRIS bits.
