Section 16 A/D Converter
16.3
The A/D converter has the following registers.
16.3.1
There are four 16-bit read-only ADDR registers, ADDRA to ADDRD (H8S/2678 Group) and
eight 16-bit read-only ADDR registers, ADDRA to ADDRH (H8S/2678R Group), used to store
the results of A/D conversion. The ADDR registers, which store a conversion result for each
channel, are shown in table 16.2.
The converted 10-bit data is stored to bits 15 to 6. The lower 6-bit data is always read as 0. ADDR
must not be accessed in 8-bit units and must be accessed in 16-bit units.
In the H8S/2678 Group, the data bus between the CPU and the A/D converter is 8-bit width. The
upper byte can be read directly from the CPU, but the lower byte should be read via a temporary
register. The temporary register contents are transferred from the ADDR when the upper byte data
is read. When reading the ADDR, read the only upper byte, or read in word unit.
In the H8S/2678R Group, the data bus between the CPU and the A/D converter is 16-bit width.
The data can be read directly from the CPU.
