s elapses before A/D conversion starts after setting the OAEN bit.
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.
