Detailed Description

Conversion-area descriptor for ra8_dotf_set_region.

Per HUM Ch 45.3 p 3049 the start and end addresses must be 4 KB aligned and start_addr <= end_addr is mandatory. The driver rejects misaligned, inverted, out-of-window or overlap-with-other- channel regions before touching hardware.

cppcheck cannot see test code, so it complains about every field being unused; ra8_dotf_set_region reads them all.
