7.0
The
comparators. The inputs to the comparators are
multiplexed with the RA0 through RA3 pins. The on-
chip voltage reference (Section 8.0) can also be an
input to the comparators.
The CMCON register, shown in Register 7-1, controls
the comparator input and output multiplexers. A block
diagram of the comparator is shown in Figure 7-1.
REGISTER 7-1:
7.1
There are eight modes of operation for the
comparators. The CMCON register is used to select
the mode. Figure 7-1 shows the eight possible modes.
The TRISA register controls the data direction of the
comparator pins for each mode. If the Comparator
mode is changed, the comparator output level may not
be valid for the specified mode change delay shown
in Table 12-1.
