Activation on Compare-Match of TMR Units
The compare-match A signal from TMR0 is capable of starting A/D conversion by units 0 and 1. In the same way, the
compare-match A signal from TMR2 is capable of starting A/D conversion by units 2 and 3.
The connections between the units of the converter and the compare-match A signals from TMR0 and TMR2 are shown
in figure 23.12.
The compare-match A signal from TMR0 is capable of simultaneously starting A/D conversion by no more than two
converter units. Setting the ADn.ADCR.TRGS[2:0] bits (n = 0, 1) to 010b (specifying the compare-match A signal from
TMR0) and setting the ADTE bit in TCSR of TMR0 to 1 set up the compare-match A signal from TMR0 as the trigger
that starts simultaneous conversion by units 0 and 1.
