Figure 8.

1. The duration that should be measured

2. In the pulse width measurement application, COMP1 cannot be used since its output CMP1OUT (internal

output) is not connected to the embedded timers.

Note:

Signal frequency can be achieved by configuring the timer input capture channel to save the

counter value on only a rising or falling edge.

Note:

DAC outputs (DAC_OUT1 or DAC_OUT2) can be used as inverting inputs to allow the

reference voltage level (threshold) to be internally provided and programmable by software

from 0 V to V
