CHAPTER 23 10-BIT A/D CONVERTER
23.4 Registers of 10-bit A/D Converter
The 10-bit A/D converter has four registers: A/D control register 1 (ADC1), A/D control
register 2 (ADC2), A/D data register H (ADDH), and A/D data register L (ADDL).

List of 10-bit A/D Converter Registers
Figure 23.4-1 lists the registers of the 10-bit A/D converter.
Figure 23.4-1 Registers of 10-bit A/D Converter
R/W: Readable/writable (Read value is the same as write value)
R0, W: Write only (Writable, "0" is read)
R/WX: Read only (Readable, writing has no effect on operation)
R0/WX: Undefined bit (Read value is 0, writing has no effect on operation)
R(RM1), W: Readable/writable (Read value is different from write value, "1" is read by read-modify-write
instruction)
