Analog Comparator Register Description
AT90PWM216/316
Analog Comparator 0 Control Register – AC0CON
Figure 20-1. Analog Comparator Block Diagram
Notes:
Each analog comparator has its own control register.
A dedicated register has been designed to consign the outputs and the flags of the 3 analog
comparators.
