ANALOG COMPARATOR (Cont’d)
Bit 4 = CMPIF Comparator Interrupt Flag
This bit is set by hardware when interrupt is gener-
ated at the rising edge (CINV = 0) or falling edge
(CINV = 1) of comparator output. This bit is
cleared by reading the CMPCR register. Writing to
this bit does not change the value.
0 : Comparator interrupt flag cleared
1 : Comparator interrupt flag set and can generate
Bit 3 : CMPIE Comparator Interrupt Enable
This bit is set or reset by software and cleared by
hardware reset. This bit enables or disables the in-
terrupt generation depending on interrupt flag
0: Interrupt not generated
1: Interrupt generated if interrupt flag is set
Note:
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
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.
0 : Comparator output not connected to PA7
1 : Comparator output connected to PA7
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.
0: Comparator, Internal Voltage Reference, Bias
1: Comparator, Internal Voltage Reference, Bias
Note: For the comparator interrupt generation, it
takes 250ns delay from comparator output change
to rising or falling edge of interrupt generated.
