User’s Manual U19678EJ1V1UD
Use the CnINV bit of CnCTL to select forwarding
or reversing of the output. Use CnDFS0 to
CnDFS2 to select the noise elimination width.
Cancel the reset state of the comparator or
programmable gain amplifier and start clock
supply.
Enable the programmable gain amplifier operation by setting
(1) the OAEN bit of OAM. 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 operation by setting (1)
the CnEN bit of CnCTL. Input to the negative
side of the comparator from the external pin will
be enabled at the same time.
Enable the comparator output signal by setting
(1) the CnOE bit of CnCTL.
Set the PM8 register to the input mode.
Set to the digital input disable
(use port8 as the analog input) state.
Set the amplification factor by using OAVG0 to
OAVG2 of OAM.
