Capture / compare (CAPCOM) units

ST10F276Z5

84/239

Mode 3

Pin set ‘1’ on match; pin reset ‘0’ on compare time overflow; only one compare event per timer

period is generated

Double Register

mode

Two registers operate on one pin; pin toggles on each compare match; several compare

events per timer period are possible.
