For a 2-line display the cursor automatically moves from the first to the second line after
the 40th digit of the first line has been written. Thus, if there are only 8 characters in the
first line, the DDRAM address must be set after the 8th character is completed
(see
together; data does not shift from one line to the other.

Operation
initialized by the external reset; no
display appears
sets to 8-bit operation; selects 2-line
display and V
turns on display and cursor; entire
display is blank after initialization
sets mode to increment the address
by 1 and to shift the cursor to the right
at the time of write to the CG/DDRAM;
display is not shifted
writes ‘P’; the DDRAM has already
been selected by initialization at
power-on; the cursor is incremented
by 1 and shifted to the right
writes ‘HILIP’
writes ‘S’
sets DDRAM address to position the
cursor at the head of the 2nd line
writes ‘M’
writes ‘ICROC’
writes ‘O’
of write
writes ‘M’; display is shifted to the left;
the first and second lines shift
together
sets mode for display shift at the time
