Detailed Description

Memory-mapped layout of one WDT instance.

The RA8D2 WDT block is 12 bytes (0x0C) wide – matches the FSP R_WDT_Type in R7KA8D2KF_core0.h exactly. Reserved padding is named _rN so the layout is unambiguous to a debugger.

See also: HUM Ch 27.2 "Register Descriptions" p 1256 (table) and the individual subsections for each register.
