Operation
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
pulse during acknowledge cycle starts
execution of instruction
turns on display and cursor; entire display
shows character code 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-on; the cursor is incremented by 1
and shifted to the right
writes ‘H’
writes ‘ILIP’
Table
Operation
returns both display and cursor to the
original position (address 0)
43).
