Address: FF60H After reset: 00H R/W
AMP0M
The operational amplifiers use the following four registers.
• Operational amplifier 0 control register (AMP0M), operational amplifier 1 control register (AMP1M)
• A/D port configuration registers 0 and 1 (ADPC0, ADPC1)
• Analog input channel specification register (ADS)
• Port mode registers 1, 2 (PM1, PM2)
Cautions 1. When using the PGA mode, use the ADPC0 register to select the PGAIN/AMP0OUT/ANI1/P21 pin
Remark The output of operational amplifier 0 is amplified by the PGA by setting OPAMP0E = PGAEN = 1.
Symbol
These registers control the operations of operational amplifiers 0 and 1.
AMP0M and AMP1M can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Remark Products with operational amplifier of the 78K0/KY2-L and 78K0/KA2-L:

0, when the operational amplifier 0 is used, make sure that the input levels of digital input ports
are fixed to prevent degradation of the A/D conversion resolution.
