5V Analog Comparator (ACMPV1)
3.4
The ACMP has two analog input signals, ACMPP and ACMPM, and one digital output, ACMPO. The
associated pins are defined by the package option.
The ACMPP signal is connected to the non-inverting input of the comparator. The ACMPM signal is
connected to the inverting input of the comparator. Each of these signals can accept an input voltage that
varies across the full 5V operating voltage range. The module monitors the voltage on these inputs
independent of any other functions in use (GPIO, ADC).
The raw comparator output signal can optionally be driven on an external pin.

1. Normal Mode
2. Shutdown Mode
The ACMP is operating when enabled and not in STOP mode.
The ACMP is held in shutdown mode either when disabled or during STOP mode. In this case the
supply of the analog block is disconnected for power saving. ACMPO drives zero in shutdown
mode.
