Description
- Positive supply voltage.
* For Ag version, apply positive supply voltage to VDD1. For other than Ag
version, apply positive supply voltage to VDD2.
- Switching pins for supplying the LCD driving voltage to the VDD1 and
VDD2 pins.
- Connect the CUP1 and CUP2 pins with the nonpolarized electrolytic capacitor
if 1/2 or 1/3 bias mode has been selected.
- In the static mode, these pins should be left open.
- Output pins for supplying voltage to drive the common pins of the LCD panel.
- Frequency can be doubled or quadrupled with PLA.
- Output pins for LCD panel segments.
* Also used as output ports with mask option.
- Test signal input pin.
