There is a Renesas-reserved section of memory that can be read but not over-written by the user.

Note: Every return starts with a status byte followed by the data word as described in section 3.5.1.

Note: The output for any ADC measurement and signal conditioning calculation is formatted as a 24-bit data word, regardless of the effective

ADC resolution used.
