A/D Data Register (ADRL: $017, ADRU: $018):
Eight-bit read-only register that is not cleared by a
reset. Note that data read from this register during A/D conversion cannot be guaranteed. After the
completion of A/D conversion, the resultant eight-bit data is held in this register, as shown in figure 36,
until the start of the next conversion.
