3. DATA OUTPUT TO LCD CONTROLLER/DRIVER (µPD16430A)
The µPD17006AGF-011 uses the µPD16430A for LCD panel display.
Initial setting data is transferred to the µPD16430A 400 to 500 ms after the CE pin (pin 31) of the
µPD17006AGF-011 has gone high.
The following figure shows the pin connections between the µPD17006AFG-011 and µPD16430A.
