14.2
14.2.1
There are four 16-bit read-only ADDR registers, ADDRA to ADDRD, used to store the results of
A/D conversion.
The 10-bit data resulting from A/D conversion is transferred to the ADDR register for the selected
channel and stored there. The upper 8 bits of the converted data are transferred to the upper byte
(bits 15 to 8) of ADDR, and the lower 2 bits are transferred to the lower byte (bits 7 and 6) and
stored. Bits 5 to 0 are always read as 0.
The correspondence between the analog input channels and ADDR registers is shown in table
14.3.
The ADDR registers can always be read by the CPU. The upper byte can be read directly, but for
the lower byte, data transfer is performed via a temporary register (TEMP). For details, see section
14.3, Interface to Bus Master.
The ADDR registers are initialized to H'0000 by a reset, and in standby mode or module stop
mode.
