: Don't care
: Address specification for each RAM
: Character code specification for each RAM
: Display duty specification
: Number of digits specification
: All lights ON instruction
: All lights OFF instruction
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.
