Chapter 9 Analog Comparator (S08ACMPV3)
9.4
The analog comparator can compare two analog input voltages applied to ACMPx+ and ACMPx−, or it
can compare an analog input voltage applied to ACMPx− with an internal bandgap reference voltage.
ACBGS selects between the bandgap reference voltage or the ACMPx+ pin as the input to the
non-inverting input of the analog comparator. The comparator output is high when the non-inverting input
is greater than the inverting input, and is low when the non-inverting input is less than the inverting input.
ACMOD selects the condition that causes ACF to be set. ACF can be set on a rising edge of the comparator
output, a falling edge of the comparator output, or a rising or a falling edge (toggle). The comparator output
can be read directly through ACO. The comparator output can be driven onto the ACMPxO pin using
ACOPE.

Functional Description
Analog Comparator Output. Reading ACO returns the current value of the analog comparator output. ACO is
reset to a 0 and reads as a 0 when the ACMP is disabled (ACME = 0).
Analog Comparator Output Pin Enable. Enables the comparator output to be placed onto the external pin,
ACMPxO.
0 Analog comparator output not available on ACMPxO
1 Analog comparator output is driven out on ACMPxO
Analog Comparator Mode. ACMOD selects the type of compare event which sets ACF.
00 Encoding 0 — Comparator output falling edge
01 Encoding 1 — Comparator output rising edge
10 Encoding 2 — Comparator output falling edge
11 Encoding 3 — Comparator output rising or falling edge
