The comparator module also allows the selection of an
internally generated voltage reference for one of the
comparator inputs. The internal reference signal is
used for four of the eight Comparator modes. The
VRCON register, Register 6-2, controls the voltage
reference module shown in Figure 6-5.
6.5.1
The voltage reference can output 32 distinct voltage
levels, 16 in a high range and 16 in a low range.
FIGURE 6-5:
6.6
Response time is the minimum time, after selecting a
new reference voltage or input source, before the
comparator output is ensured to have a valid level. If
the internal reference is changed, the maximum delay
of the internal voltage reference must be considered
when using the comparator outputs. Otherwise, the
maximum delay of the comparators should be used
(Table 12-7).
6.7
Both the comparator and voltage reference, if enabled
before entering Sleep mode, remain active during
Sleep. This results in higher Sleep currents than shown
in the power-down specifications. The additional cur-
rent consumed by the comparator and the voltage ref-
erence is shown separately in the specifications. To
minimize power consumption while in Sleep mode, turn
off the comparator, CM2:CM0 = 111, and voltage refer-
ence, VRCON<7> = 0.

While the comparator is enabled during Sleep, an inter-
rupt will wake-up the device. If the device wakes up
from Sleep, the contents of the CMCON and VRCON
registers are not affected.
6.8
A device Reset forces the CMCON and VRCON
registers to their Reset states. This forces the
comparator module to be in the Comparator Reset
mode, CM2:CM0 = 000 and the voltage reference to its
off state. Thus, all potential inputs are analog inputs
with the comparator and voltage reference disabled to
consume the smallest current possible.
