H'FFFD000 (address Y) + H'08C0 (value X), or H'FFFFD8C0. As a result, H'0230 is written to
the SDMR register. When H'0230 is written to the SDMR register of area 3, random data is
written to the address H'FFFE000 (address Y) + H'08C0 (value X) or H'FFFFE8C0. As a result,
H'0230 is written to the SDMR register. The range for value X is H'000 to H'0FFC.
Note: Depending on the type of synchronous DRAM.
10.2.9
The refresh timer control/status register (RTSCR) is a 16-bit read/write register that specifies the
refresh cycle, whether to generate an interrupt, and the cycle of that interrupt. RTSCR is initialized
to H'0000 by a power-on reset, but is not initialized by a manual reset or in standby mode.
Note: The method for writing to RTCOR is different from that for general registers to prevent
Bits 15 to 8—Reserved: These bits always read 0.

inadvertent overwriting. Using a word transfer instruction, place B'10100101 in the upper
byte and the write data in the lower byte. For details, see section 10.2.13, Cautions on
