16.2
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:
• 8T
• 32T
• 64T
• Internal RC oscillator

Selecting the A/D Conversion
Clock
When the device frequency is greater than 1 MHz, the RC A/D conversion clock source is only
recommended for SLEEP operation.
When the device frequency is greater than 1 MHz, the RC A/D conversion clock source is only
