Section 27
27.3
The A/D converter has the following registers.
• A/D data register A (ADDRA)
• A/D data register B (ADDRB)
• A/D data register C (ADDRC)
• A/D data register D (ADDRC)
• A/D control/status register (ADCSR)
27.3.1
The four A/D data registers (ADDRA to ADDRD) are 16-bit read-only registers that store the
results of A/D conversion.
An A/D conversion produces 10-bit data, which is transferred for storage into the A/D data
register corresponding to the selected channel. The upper 8 bits of the result are stored in the upper
byte (bits 15 to 6) of the A/D data register. Bits 5 to 0 of an A/D data register are always read as 0.
Table 27.2 indicates the pairings of analog input channels and A/D data registers.
Each ADDR is initialized to H'0000 by a reset and the module standby function and in standby
mode.
