1. Outline

A comparator (COMP) compares analog input voltage (AINA00 or AINA01) with reference voltage, and
outputs the result to EMG input on Advanced Programmable Control Circuit(A-PMD).

2. Configuration
A comparator compares voltage input (VINC) from AINA00 or AINA01 with reference voltage (VREFC:
channel 0 of built-in 8-bit digital to analog converter(DAC) output). A comparative result (COMP output) is
outputted to the EMG input of A-PMD.
