DISPLAY
initialized; no display appears
during the acknowledge cycle SDA will be pulled-down by the
PCF2119x
control byte sets RS for following data bytes
selects 1-line display and V
acknowledge cycle starts execution of instruction
turns on display and cursor; entire display shows character 20H
(blank in ASCII-like character sets)
sets mode to increment the address by 1 and to shift the cursor
to the right at the time of write to the DDRAM or CGRAM; display
is not shifted
for writing data to DDRAM, RS must be set to 1; therefore a
control byte is needed
writes ‘P’; the DDRAM has been selected at power-up; the
cursor is incremented by 1 and shifted to the right
writes ‘H’
