Bit7: CPnEN: Comparator Enable Bit. (Please see note below.)
0: Comparator Disabled.
1: Comparator Enabled.
Bit6: CPnOUT: Comparator Output State Flag.
0: Voltage on CPn+ < CPn–.
1: Voltage on CPn+ > CPn–.
Bit5: CPnRIF: Comparator Rising-Edge Interrupt Flag.
0: No Comparator Rising Edge Interrupt has occurred since this flag was last cleared.
1: Comparator Rising Edge Interrupt has occurred. Must be cleared by software.
Bit4: CPnFIF: Comparator Falling-Edge Interrupt Flag.
0: No Comparator Falling-Edge Interrupt has occurred since this flag was last cleared.
1: Comparator Falling-Edge Interrupt has occurred. Must be cleared by software.
Bits3-2: CPnHYP1-0: Comparator Positive Hysteresis Control Bits.
00: Positive Hysteresis Disabled.
01: Positive Hysteresis = 5 mV.
10: Positive Hysteresis = 10 mV.
11: Positive Hysteresis = 20 mV.
Bits1-0: CPnHYN1-0: Comparator Negative Hysteresis Control Bits.
00: Negative Hysteresis Disabled.
01: Negative Hysteresis = 5 mV.
10: Negative Hysteresis = 10 mV.
11: Negative Hysteresis = 20 mV.
NOTE: Upon enabling a comparator, the output of the comparator is not immediately valid. Before
using a comparator as an interrupt or reset source, software should wait for a minimum of
the specified “Power-up time” as specified in Table 11.1, “Comparator Electrical Characteris-
tics,” on page 126.
