0 Test mode

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.
