CMPx_SCR field descriptions (continued)
Field Description
5
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
4
IER
Comparator Interrupt Enable Rising
Enables the CFR interrupt from the CMP. When this field is set, an interrupt will be asserted when CFR is
set.
0 Interrupt is disabled.
1 Interrupt is enabled.
3
IEF
Comparator Interrupt Enable Falling
Enables the CFF interrupt from the CMP. When this field is set, an interrupt will be asserted when CFF is
set.
0 Interrupt is disabled.
1 Interrupt is enabled.
2
CFR
Analog Comparator Flag Rising
Detects a rising-edge on COUT, when set, during normal operation. CFR is cleared by writing 1 to it.
During Stop modes, CFR is edge sensitive .
0 Rising-edge on COUT has not been detected.
1 Rising-edge on COUT has occurred.
1
CFF
Analog Comparator Flag Falling
Detects a falling-edge on COUT, when set, during normal operation. CFF is cleared by writing 1 to it.
During Stop modes, CFF is edge sensitive .
0 Falling-edge on COUT has not been detected.
1 Falling-edge on COUT has occurred.
0
COUT
Analog Comparator Output
Returns the current value of the Analog Comparator output, when read. The field is reset to 0 and will read
as CR1[INV] when the Analog Comparator module is disabled, that is, when CR1[EN] = 0. Writes to this
field are ignored.
