8-bit microcontroller with 10-bit ADC
7.22.1 Internal reference voltage
An internal reference voltage generator may supply a default reference when a single
comparator input pin is used. The value of the internal reference voltage, referred to as
Vref(bg), is 1.23 V ± 10 %.
7.22.2 Comparator interrupt
Each comparator has an interrupt ag contained in its conguration register. This ag is
set whenever the comparator output changes state. The ag may be polled by software or
may be used to generate an interrupt. The two comparators use one common interrupt
vector. If both comparators enable interrupts, after entering the interrupt service routine,
the user needs to read the ags to determine which comparator caused the interrupt.
7.22.3 Comparators and power reduction modes
Either or both comparators may remain enabled when Power-down or Idle mode is
activated, but both comparators are disabled automatically in Total Power-down mode.
If a comparator interrupt is enabled (except in Total Power-down mode), a change of the
comparator output state will generate an interrupt and wake-up the processor. If the
comparator output to a pin is enabled, the pin should be congured in the push-pull mode
in order to obtain fast switching times while in Power-down mode. The reason is that with
the oscillator stopped, the temporary strong pull-up that normally occurs during switching
on a quasi-bidirectional port pin does not take place.
Comparators consume power in Power-down and Idle modes, as well as in the normal
operating mode. This fact should be taken into account when system power consumption
is an issue. To minimize power consumption, the user can disable the comparators via
PCONA.5, or put the device in Total Power-down mode.
