OAM
(2) Programmable gain amplifier control register (OAM)
This register is used to enable or disable the operation of a programmable gain amplifier and set the amplification
factor.
The OAM register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. Set the amplification factor before enabling (OAEN = 1) the operation of the programmable
