PIC16F/LF1826/27
18.2
Each comparator has 2 control registers: CMxCON0 and
CMxCON1.
The CMxCON0 registers (see Register 18-1) contain
Control and Status bits for the following:
• Enable
• Output selection
• Output polarity
• Speed/Power selection
• Hysteresis enable
• Output synchronization
The CMxCON1 registers (see Register 18-2) contain
Control bits for the following:
• Interrupt enable
• Interrupt edge polarity
• Positive input channel selection
• Negative input channel selection
18.2.1
Setting the CxON bit of the CMxCON0 register enables
the comparator for operation. Clearing the CxON bit
disables the comparator resulting in minimum current
consumption.
18.2.2
The output of the comparator can be monitored by
reading either the CxOUT bit of the CMxCON0 register
or the MCxOUT bit of the CMOUT register. In order to
make the output available for an external connection,
the following conditions must be true:
• CxOE bit of the CMxCON0 register must be set
• Corresponding TRIS bit must be cleared
• CxON bit of the CMxCON0 register must be set

latched with each instruction cycle.
Unless otherwise specified, external
outputs are not latched.
Preliminary
18.2.3
Inverting the output of the comparator is functionally
equivalent to swapping the comparator inputs. The
polarity of the comparator output can be inverted by
setting the CxPOL bit of the CMxCON0 register.
Clearing the CxPOL bit results in a non-inverted output.
Table 18-1 shows the output state versus input
conditions, including polarity control.
TABLE 18-1:
18.2.4
The trade-off between speed or power can be opti-
mized during program execution with the CxSP control
bit. The default state for this bit is ‘1’ which selects the
normal speed mode. Device power consumption can
be optimized at the cost of slower comparator propaga-
tion delay by clearing the CxSP bit to ‘0’.
