UM0404 The capture / compare units
Figure 134. CAPCOM unit block diagram
Note: The CAPCOM2 unit provides 16 capture inputs, but only 12 compare outputs.
16.1 CAPCOM timers
The primary use of the timers T0 / T1 and T7 / T8 is to provide two independent time bases
for the capture / compare registers of each unit, but they may also be used independent of
the capture / compare registers. The basic structure of the four timers is identical, while the
selection of input signals is different for timers T0 / T7 and timers T1 / T8.
