This bit should be set to enable interrupt only after the comparator has been switched ON,
i.e. when CMPON is set.
Once CMPON bit is set, it is recommended to wait the specified stabilization time before
setting CMPIE bit in order to avoid a spurious interrupt (see analog comparator
characteristics in
Bit 2 : CMP Comparator output
This bit is set or reset by software and cleared by hardware reset. It stores the value of
comparator output.
Bit 1 = COUT Comparator output enable on Port
This bit is set or cleared by software. When this bit is set, the comparator output is available
on PA7 port.
Bit 0 : CMPON Comparator ON/OFF
This bit is set or cleared by software and reset by hardware reset. This bit is used to switch
ON/OFF the comparator, internal voltage reference and current bias which provides 4µA
current to both.
For the comparator interrupt generation, it takes 250 ns delay from comparator output
change to rising or falling edge of interrupt generated.

0 : Comparator interrupt flag cleared
1 : Comparator interrupt flag set and can generate interrupt if CMPIE is set.
0: Comparator, internal voltage reference, Bias OFF (in power-down state).
