Write Data
to RAM
1 0 D7 D6 D5 D4 D3 D2 D1 D0
43us Write data into internal RAM
( DDRAM/CGRAM )
Read Data 1 1 D7 D6 D5 D4 D3 D2 D1 D0
from RAM
43us Read data from internal RAM
( DDRAM/CGRAM )
NOTE : When you make an MPU program with checking the Bus Flag (DB7), it must be necessary 1/2 Fosc for
executing the next instruction by falling E signal after the Busy Flag (DB7) goes to "0" .
