10.5.9
MCR is a 32-bit readable/writable register that specifies RAS and CASS timing, burst control,
address multiplexing, and refresh control for synchronous DRAM (areas 2 and 3).
Write bits 31 to 3 when making the initial settings after a power-on reset and do not modify the
settings from then onward. When writing to bits RFSH and RMODE, write the same values
without changing other bits. When using synchronous DRAM, do not access areas 2 and 3 before
register initialization is complete.
