6.1
A single comparator is shown in Figure 6-1, along with
the relationship between the analog input levels and
the digital output. When the analog input at V
than the analog input V
is a digital low level. When the analog input at V
greater than the analog input V
comparator is a digital high level. The shaded areas of
the output of the comparator in Figure 6-1 represent
the uncertainty due to input offsets and response time.
The polarity of the comparator output can be inverted
by setting the CINV bit (CMCON<4>). Clearing CINV
results in a non-inverted output. A complete table
showing the output state versus input conditions and
the polarity bit is shown in Table 6-1.

Note:
Comparator Operation
To use CIN+ and CIN- pins as analog
inputs, the appropriate bits must be
programmed in the CMCON (19h) register.
