14.2
14.2.1
A/D data registers 0 to 15 (ADDR0 to ADDR15) are 16-bit read-only registers that store the
results of A/D conversion. There are 16 registers, corresponding to analog inputs 0 to 15 (AN0 to
AN15).
The ADDR registers are initialized to H'0000 by a power-on reset, and in hardware standby mode
and software standby mode.
The A/D converter converts analog input to a 10-bit digital value. The upper 8 bits of this data are
stored in the upper byte of the ADDR corresponding to the selected channel, and the lower 2 bits
in the lower byte of that ADDR. Only the most significant 2 bits of the ADDR lower byte data are
valid.
Table 14.3 shows correspondence between the analog input channels and A/D data registers.
