B7
Unimplemented. Read as ‘0’.
B6
CMBOUT
Comparator B Output
Reading this bit returns the status of the comparator B output. Writes to this bit have no
effect.
B5
CMBOE
Comparator B Output Enable
1 = Comparator B output is available on RD2/CMPB pin and Reference B output is
available on RD3/REFB pin.
0 = RD2/CMPB and RD3/REFB assume normal PORTD function.
B4
CPOLB
Comparator B Polarity Bit
1 = Invert the output of comparator B.
0 = Do not invert the output of comparator B.
B3
Unimplemented. Read as ‘0’.
B2
CMAOUT
Comparator A Output
Reading this bit returns the status of the comparator A output. Writes to this bit have no
effect.
B1
CMAOE
Comparator A Output Enable
1 = Comparator A output is available on RC1/CMPA pin and Reference A output is
available on RC0/REFA pin.
0 = RC0/REFA and RC1/CMPA assume normal PORTC function.
B0
CPOLA
Comparator A Polarity Bit
1 = Invert the output of comparator A.
0 = Do not invert the output of comparator A.
