(5) Operational amplifier n control register 0 (OPnCTL0) (n = 0, 1)
Note In the V850E/IA3, this bit can be set only when A/D converter 1 is used. This bit must be cleared to 0
Cautions 1. Be sure to clear bits 1 to 3 and 7 to “0”.
The OPnCTL0 register is an 8-bit register that controls the operation of the operational amplifier for input level
amplification and specifies the gain.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
