Set the PM8 register to the input mode.
Set to the digital input disable
(use port8 as the analog input) state.
Cancel the reset state of the comparator or
programmable gain amplifier and start clock
supply.
Set the amplification factor by using OAVG0 to
OAVG2 of OAM.
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.
