Symbol
OAM
(2) Programmable gain amplifier control register (OAM)
This register is used to enable or disable the operation of an programmable gain amplifier and set the
amplification factor.
OAM 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
