Interface Pin Function

Pin No.	Symbol	Level	Description
1	P/S	I	This is the parallel data input/serial data input switch terminal.
2	C86	I	This is the MPU interface switch terminal.
3	VR	I	Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
4~8	V0~V4	Power supply	This is a multi-level power supply for the liquid crystal drive.
9	CAP2N	O	DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.
10	CAP2P	O	DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.
11	CAP1P	O	DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
12	CAP1N	O	DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.
13	CAP3P	O	DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
14	VOUT	O	DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD
15	VSS	Power supply	Ground
16	VDD	Power supply	Power supply
17~24	D7~D0	I/O	This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
25	/RD(E)	I	The data bus is in output status when this signal is “L”
26	/WR(R/W)	I	The data bus are latched at the rising edge of the WR signal
27	A0	I	This is connect to the least significant bit of the Norman MPU address bus, and it determines whether the data bits are data or a command.
28	/RES	I	When RES is set to “L”, the setting are initialized.
29	/CS1	I	This is the chip select signal.
