Bit 7 – INVERT: Invert AC Output

Invert AC Output

Writing this bit to ‘1’ enables inversion of the output of the AC. This inversion has to be taken into account when using the AC output signal as an input signal to other peripherals or parts of the system.

Bit 6 – INITVAL: AC Output Initial Value

AC Output Initial Value

To avoid that the AC output toggles before the comparator is ready, the INITVAL can be used to set the initial state of the comparator output.
ValueNameDescription
0x0 LOW Output initialized to ‘0
0x1 HIGH Output initialized to ‘1
