Description
[7:6]
POSSEL
Comparator 0 Positive Input Selection
00 = ACMP0_P0 (P2.5) pin.
01 = ACMP0_P1 (P2.3) pin.
10 = ACMP0_P2 (P2.1) pin.
11 = ACMP0_P3 (P3.0) pin.
[5:4]
NEGSEL
Comparator 0 Negative Input Selection
00 = ACMP0_N0 (P2.4) pin.
01 = Internal comparator reference voltage (CRV).
10 = VBG (Band-gap).
11 = ACMP0_N1 (P2.0)pin.
[3]
WKEN
Comparator 0 Power-Down Wake-Up Enable Bit
0 = Comparator 0 Wake-up function Disabled.
1 = Comparator 0 Wake-up function Enabled.
[2]
HYSEN
Comparator 0 Hysteresis Enable Bit
0 = Comparator 0 hysteresis Disabled.
1 = Comparator 0 hysteresis Enabled.
[1]
ACMPIE
Comparator 0 Interrupt Enable Bit
0 = Comparator 0 interrupt Disabled.
1 = Comparator 0 interrupt Enabled. If WKEN (ACMPCR1[3]) is set to 1, the wake-up interrupt
function will be enabled as well.
[0]
ACMPEN
Comparator 0 Enable Bit
0 = Comparator 0 Disabled.
1 = Comparator 0 Enabled.
