5V Analog Comparator (ACMPV1)

The following setup is recommended to control an external component:

1. Route internal monitoring signals to ACMP inputs: PRR2[ACROV]=1

2. Enable ACMP raw signal output on ACMPO1 pin: PRR2[ACOPE1]=1

3. Select desired ACMPO1 output polarity by setting PRR2[ACOPS]

4. Conï¬gure ACMP to trigger on rising edge: ACMPC[ACMOD1:ACMOD0]=0b01

5. Enable ACMP: ACMCP[ACE]=1

NOTE

Operation of the device with supply VDD35 between maximum speciï¬ed

operating voltage and Vassert(max) must be limited over total lifetime (refer

to operating conditions in App. A). The TJ(max) speciï¬cation must be

obeyed.
