4
Entry_mode_set
0000000110
sets mode to increment the address
by 1 and to shift the cursor to the right
at the time of the write to the
DDRAM/CGRAM; display is not shifted
5

1001010000P
writes ‘P’; the DDRAM has already
been selected by initialization at
power-on; the cursor is incremented
by 1 and shifted to the right
