When data is written to RAM (DCRAM, CGRAM, ADRAM) continuously, addresses are internally incremented
automatically. Therefore it is not necessary to specify the 1st byte to write RAM data for the 2nd and later bytes.
Note :
The test mode is used for inspection before shipment.
It is not a user function.
