EXAMPLE 16-1:
16.15 Changing A/D Clock
In general, the ADC cannot accept changes to the ADC
clock divisor while ADON = 1. If the user makes A/D
clock changes while ADON = 1, the results will be
indeterminate.
16.16 Sample and Conversion
The ADC module always assigns two ADC clock peri-
ods for the sampling process. When operating at the
maximum conversion rate of 2 Msps per channel, the
sampling period is:

Preliminary
Each ADC pair specified in the ADCPCx registers ini-
tiates a sample operation when the selected trigger
event occurs. The conversion of the sampled analog
data occurs as resources become available.
If a new trigger event occurs for a specific channel
before a previous sample and convert request for that
channel has been processed, the newer request is
ignored. It is the user’s responsibility not to exceed the
conversion rate capability for the module.
The actual conversion process requires 10 additional
ADC clocks. The conversion is processed serially, bit 9
first, then bit 8, down to bit 0. The result is stored when
the conversion is completed.
