Section 12 A/D Converter
12.2
12.2.1
ADRRH and ADRRL together comprise a 16-bit read-only register for holding the results of
analog-to-digital conversion. The upper 8 bits of the data are held in ADRRH, and the lower 2
bits in ADRRL.
ADRRH and ADRRL can be read by the CPU at any time, but the ADRRH and ADRRL values
during A/D conversion are not fixed. After A/D conversion is complete, the conversion result is
stored as 10-bit data, and this data is held until the next conversion operation starts.
ADRRH and ADRRL are not cleared on reset.
12.2.2
AMR is an 8-bit read/write register for specifying the A/D conversion speed, external trigger
option, and the analog input pins.
Upon reset, AMR is initialized to H'30.
