16.17 A/D Sample and Convert Timing
The sample and hold circuits assigned to the input pins
have their own timing logic that is triggered when an
external sample and convert request (from PWM or
TMR) is made. The sample and hold circuits have a
fixed two clock data sample period. When the sample
has been acquired, then the ADC control logic is noti-

fied of a pending request, then the conversion is
performed as the conversion resources become
available.
The ADC module always converts pairs of analog input
channels, so a typical conversion process requires 24
clock cycles.
