Note)
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.

: Don’t care
Xn : Address specification for each RAM
Cn : Character code specification for each RAM
Dn : Display duty specification
Kn : Number of digits specification
H
: All lights ON instruction
L
: All lights OFF instruction
Note: The test mode is used for inspection before shipment.
It is not a user function. The user cannot use this
command. Enter commands 1 to 3, 5 to 7, 9 to B, and
F alone in the way described on the next page and the
following pages. (The operation of this device cannot be
guaranteed if other commands are used.)
