12.2
12.2.1
The A/D result register (ADRR) is an 8-bit read-only register for holding the results of analog-to-
digital conversion.
ADRR can be read by the CPU at any time, but the ADRR values during A/D conversion are not
fixed.
After A/D conversion is complete, the conversion result is stored in ADRR as 8-bit data; this data
is held in ADRR until the next conversion operation starts.
ADRR is 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.
