Bits 20:18 BLANKING[2:0]: Comparator 1 blanking source selection bits
These bits select which timer output controls the comparator 1 output blanking.
000: No blanking
001: TIM1 OC5 selected as blanking source
010: TIM2 OC3 selected as blanking source
100: TIM3 OC3 selected as blanking source
All other values: reserved
Bits 17:16 HYST[1:0]: Comparator 1 hysteresis selection bits
These bits are set and cleared by software (only if LOCK not set). They select the
Hysteresis voltage of the comparator 1.
00: No hysteresis
01: Low hysteresis
10: Medium hysteresis
11: High hysteresis
Bit 15 POLARITY: Comparator 1 polarity selection bit
This bit is set and cleared by software (only if LOCK not set). It inverts Comparator 1
polarity.
0: Comparator 1 output value not inverted
1: Comparator 1output value inverted
Bits 14:8 Reserved, must be kept at reset value.
Bit 7 INPSEL: Comparator1 input plus selection bit
This bit is set and cleared by software (only if LOCK not set).
0: external IO - PC5
1: PB2
Bits 6:4 INMSEL: Comparator 1 input minus selection bits
These bits are set and cleared by software (only if LOCK not set). They select which input is
connected to the input minus of comparator 1.
000 = 1/4 V
REFINT
001 = 1/2 V
REFINT
010 = 3/4 V
REFINT
011 = V
REFINT
100 = DAC Channel1
101 = DAC Channel2
110 = PB1
111 = PC4
Bits 3:2 PWRMODE[1:0]: Power Mode of the comparator 1
These bits are set and cleared by software (only if LOCK not set). They control the
power/speed of the Comparator 1.
00: High speed
01 or 10: Medium speed
11: Ultra low power
Bit 1 Reserved, must be kept cleared.
Bit 0 EN: Comparator 1 enable bit
This bit is set and cleared by software (only if LOCK not set). It switches on Comparator1.
0: Comparator 1 switched OFF
1: Comparator 1 switched ON
