IRR8 is an 8-bit register that indicates whether interrupt requests from the SDHI, MMC, and
AFEIF are generated. This register is initialized to H'00 by a power-on reset or manual reset, but is
not initialized in standby mode.
Note: Note: On the models not having the SDHI, the SDHI-related bits are reserved. The write
