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.
Kn : Number of digits specification

L
: All lights ON instruction
: All lights OFF instruction
Note: The test mode is used for inspection before shipment.
It is not a user function.
