Auto Operation Mode
When TCHA2 bit of Touch ADC Control register is set to "0", BU26154MUV is set to Auto Operation Mode. When is to set
in Auto Mode Operation, BU 26154 MUV is Interrupt mode by reading to ADCR2 register in 12 bit mode and BU 26154
MUV is Interrupt mode by reading to ADCR1 register in 8 bit mode.
