7.17.1 Features
7.18 Analog comparator
The analog comparator with selectable hysteresis can compare voltage levels on external
pins and internal voltages. See
After power-up and after switching the input channels of the comparator, the output of the
voltage ladder must be allowed to settle to its stable value before it can be used as a
comparator reference input. Settling times are given in
Fig 8.

Power-down mode.
Conversion speed controlled via a programmable bias current.
Optional output update modes:
– write operations to the DAC register.
– a transition of pins ATRG0 or ATRG1. Input signals must be held for a minimum of
– a timer match signal.
– a comparator output signal held for a minimum of two system clock periods.
Holds output value during Sleep mode if the DAC is not powered down.
