Programmable Gain Amplifier)
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 register. Input to the
negative side of the comparator from the external
pin will be enabled at the same time.
Set the PM8 register to the input mode.
Set to the digital input disable state
(use port 8 as the analog input).
Cancel the reset state of the comparator or
programmable gain amplifier and start clock
supply.
Set the amplification factor by using the OAVG0 to
OAVG2 bits of the OAM register.
Enable the programmable gain amplifier operation by setting
(1) the OAEN bit of the OAM register. At the same time,
enable the external input from the programmable gain
amplifier input pin (PGAI). The programmable gain amplifier
output signal will be input as the positive-side input voltage of
the comparator.
Enable the comparator output signal by setting
(1) the CnOE bit of the CnCTL register.
