Start
μ
(Using Only a Comparator)
Cancel the reset state of the comparator or
programmable gain amplifier and start clock
supply.
Select the internal reference voltage by using the
CnVRS0 to CnVRS2 bits of the CnRVM regster.
Set to use the internal reference voltage by
setting (1) the CnVRE bit of the CnRVM
regster. The internal reference voltage will be
input to the negative side of the comparator at
the same time.
Enable the comparator output signal by setting
(1) the CnOE bit of the CnCTL regster.
Set the PM8 register to the input mode.
Set to the digital input disable state
(use port 8 as the analog input).
Use the CnINV bit of the CnCTL register to select
forwarding or reversing of the output. Use the
CnDFS0 to CnDFS2 bits to select the noise
elimination width.
Enable the comparator operation by setting (1) the
CnEN bit of the CnCTL regster. Input to the
positive side of the comparator from the external
pin will be enabled at the same time.
