FUNCTION

TRST = H (Display off)

Making /DISP low sets the D1 flag to 0 and the D0 flag to 0 (D1 =

1

DISP

D0 = 0) in the driver output control register (08h) and turns OFF the

display. To light the display after it has been turned OFF by this pin,

make /DISP high and set the D1 flag to 1 and the D0 flag to 1

(D1 = 1, D0 = 1).

2

VSS

Ground pin, connected to 0 V

3

VCC

This pin is the power supply pin for EEPROM. connects to +2.7 V to +5.5 V

4

VDD

Power supply pin, connects to +2.4 V to +3.3 V

The pin is chip select signal pin. When /CS1 = L, the

5

/CS1

chip is active, and data/commands can be input or output and I/O manipulated.

This pin is usually connected to the least significant bit of a standard CPU

address bus to identify whether data is an index register or data/command.

6

RS

RS = H: Indicates that D0 to D7 or D0 to D15 are data/command.

RS = L: Indicates that D0 to D7 or D0 to D15 are an index register.

When i80 system parallel data transfer is selected (/WR), write is enabled

by this signal. Data is written at the rising edge of this signal. When M68

7

/WR

system parallel data transfer is selected, this pin determines the

data transfer direction, as follows:

0: Write 1: Read

When i80 system parallel data transfer is selected (/RD), read is enabled

by this signal. When this pin is L, data is output to the data bus. When

8

/RD

M68 system parallel data transfer is selected, this pin inputs an enable

signal that triggers data write or read.
