18.6.2 Comparator 2 control and status register (COMP2_CSR)
Address offset: 0x04
System reset value: 0x0000 0000
Bit 11 WINMODE: Comparator 1 non-inverting input selector for window mode
This bit is controlled by software (if not locked). It selects the signal for COMP1_INP input of
the comparator 1:
0: Signal selected with INPSEL[1:0] bitfield of this register
1: COMP2_INP signal of the comparator 2 (required for window mode, see Figure 69)
Bit 10 Reserved, must be kept at reset value
Bits 9:8 INPSEL[1:0]: Comparator 1 signal selector for non-inverting input
This bitfield is controlled by software (if not locked). It selects the signal for the non-inverting
input COMP1_INP of the comparator 1 (also see the WINMODE bit):
00: PC5
01: PB2
10: PA1
11: None (open)
Bits 7:4 INMSEL[3:0]: Comparator 1 signal selector for inverting input INM
This bitfield is controlled by software (if not locked). It selects the signal for the inverting
input COMP1_INM of the comparator 1:
0000: 1/4 V
