In case of changing the data of CRAM and OFRAM data at RUN state, execute preparation of writing data at run

state(in this case, address is unnecessary and RST is "H") by writing to buffer memory similar to Fig.11. Secondary,

set WRQ to "L" and if input of command code and address is finished then set WRQ to "H". If the preparation for

rewrite is finished inside, WRDY signal becomes "L", and rewrite command is executed from rising of LRCK. And if

rewriting is finished, WRDY becomes to "H". These timing is shown in Fig.41.
