16.2
The ACMP has two analog input pins, ACMP+ and ACMP– and one digital output pin ACMPO. Each of
these pins can accept an input voltage that varies across the full operating voltage range of the MCU. As
shown in
ACMP+ pin is connected to the comparator non-inverting input if ACBGS is a 0. As shown in
the ACMPO pin can be enabled to drive an external pin.
The signal properties of ACMP are shown in
16.3
The ACMP includes one register:
Refer to the direct-page register summary in the memory section of this data sheet for the absolute address
assignments for all ACMP registers.This section refers to registers and control bits only by their names and
relative address offsets.
Some MCUs may have more than one ACMP, so register names include placeholder characters to identify
which ACMP is being referenced.
