11.2
The A/D conversion time per bit is defined as T
A/D conversion requires a minimum 12T
conversion. The source of the A/D conversion clock is
software selected. The four possible options for T
are:
• 2T
• 8T
• 32T
• Internal A/D module RC oscillator (2-6 s)
TABLE 11-1:
11.3
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: The RC source has a typical T
