COMPARATOR(S)
This
device
contains
two
comparators
and
a
comparator voltage reference.
REGISTER 9-1:
CM1CON0: COMPARATOR C1 CONTROL REGISTER
R-1
R/W-1
C1OUT
C1OUTEN
C1POL
C1T0CS
C1ON
C1NREF
C1PREF
C1WU
bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
C1OUT: Comparator Output bit
1
= VIN+ > VIN-
0
= VIN+ < VIN-
bit 6
C1OUTEN: Comparator Output Enable bit(1), (2)
1
= Output of comparator is NOT placed on the C1OUT pin
0
= Output of comparator is placed in the C1OUT pin
bit 5
C1POL: Comparator Output Polarity bit(2)
1
= Output of comparator is not inverted
0
= Output of comparator is inverted
bit 4
C1T0CS: Comparator TMR0 Clock Source bit(2)
1
= TMR0 clock source selected by T0CS control bit
0
= Comparator output used as TMR0 clock source
bit 3
C1ON: Comparator Enable bit
1
= Comparator is on
0
= Comparator is off
bit 2
C1NREF: Comparator Negative Reference Select bit(2)
1
= C1IN- pin
0
= 0.6V VREF
bit 1
C1PREF: Comparator Positive Reference Select bit(2)
1
= C1IN+ pin
0
= C1IN- pin
bit 0
C1WU: Comparator Wake-up On Change Enable bit(2)
1
= Wake-up On Comparator Change is disabled
0
= Wake-up On Comparator Change is enabled
Note 1:
Overrides T0CS bit for TRIS control of RB2.
2: When comparator is turned on, these control bits assert themselves. Otherwise, the other registers have
precedence.
