• Values of ADREG08L/ADREG19L read from bits 5 through 2 are always "1".
• Bit 0 of ADREG08L/ADREG19L is the A/D conversion result storage flag . This bit is set to "1"
after an A/D converted value is stored. A read of a lower register (ADREGxL) will set this bit to "0".
• Bit 1 of ADREG08L/ADREG19L is the over RUN flag . This bit is set to "1" if a conversion result is
overwritten before both conversion result storage registers (ADREGxH and ADREGxL) are read. A read of a
flag will clear this bit to "0."
• To read from conversion result storage registers, first read upper registers and then lower registers.
