7. Write to character RAM for user definition
Segment ON/OFF data is written into the character RAM for
user definition (35 bits). After write to RAM is declared at the
first byte, RAM is selected at the second byte and ON/OFF
data is transmitted at the 3rd to 7th byte. Therefore, write to
RAM is executed by a 7-byte command.
Character codes from RAM1 to RAM 16 are assigned to data
from 9016 to 9F16 respectively.

in the following table should be
transmitted in serial order.
