13. Bus State Controller (BSC)
command is issued in the TMw1 cycle by setting MCR.MRSET to 1 and performing a write to
address H'FF900000 + X or H'FF940000 + X.
Synchronous DRAM mode register setting should be executed once only after power-on reset and
before synchronous DRAM access, and no subsequent changes should be made.
