Field Description
3
INV
Comparator INVERT
Allows selection of the polarity of the analog comparator function. It is also driven to the COUT output, on
both the device pin and as SCR[COUT], when OPE=0.
0 Does not invert the comparator output.
1 Inverts the comparator output.
2
COS
Comparator Output Select
0 Set the filtered comparator output (CMPO) to equal COUT.
1 Set the unfiltered comparator output (CMPO) to equal COUTA.
1
OPE
Comparator Output Pin Enable
0 CMPO is not available on the associated CMPO output pin. If the comparator does not own the pin,
this field has no effect.
1
CMPO is available on the associated CMPO output pin.
The comparator output (CMPO) is driven out on the associated CMPO output pin if the comparator
owns the pin. If the comparator does not own the field, this bit has no effect.
0
EN
Comparator Module Enable
Enables the Analog Comparator module. When the module is not enabled, it remains in the off state, and
consumes no power. When the user selects the same input from analog mux to the positive and negative
port, the comparator is disabled automatically.
0 Analog Comparator is disabled.
1 Analog Comparator is enabled.

CMPx_FPR field descriptions
Field Description
FILT_PER Filter Sample Period
Specifies the sampling period, in bus clock cycles, of the comparator output filter, when CR1[SE]=0.
Setting FILT_PER to 0x0 disables the filter. Filter programming and latency details appear in the
Functional description .
