Detailed Description

SDRAM controller register window.

Offsets verified against HUM Ch 15 "Buses" and the FSP CMSIS R_BUS->SDRAM definition. Reserved-field sizes are computed from ra8_sdramc_off_t, so a register-type change is caught by the layout static_asserts below.

Invariant

SDTR sits at +0x44 and SDSR at +0x50.
