The RAMs are set by command data using the IFDI signal.
2
The first byte after the I
C address (32h) is a command, which differs for each RAM. The next two bytes contain the start address for each RAM.
The length of the data field following the RAM address bytes is 2 × n bytes. The address is automatically incremented by 1.
During program running, 1 word of data is written at a time in internal RAM synchronizing with a SYNC signal.
Therefore, when performing continuously two or more write to word, unless it applies more than 1/fs [sec] per 1 word and it sets up, taking in of data is not
performed correctly.
At the time of program STOP, it is written in asynchronous.
