*1: Command ld.a accesses 32-bit memory. When data is transferred from register to memory, 32 bits of data with
the first 8 bits set to 0 are written to memory. When data is read from memory, the first 8 bits are ignored.
*2: Coprocessor commands are reserved, since the S1C17001 does not include a coprocessor.
