Description

Clock oscillating pins required for internal operation upon receipt

of the LCD drive signal and CPU instruction.

Reset pin

Selection pin for either 68 series CPU or 80 series CPU

Chip select pin. By setting CS at "L" level, MSM6262-xx

is set at selecting condition.

R/W pin of 68 series CPU shall be connected to this pin,

while WR pin shall be connected to this pin in the case of

80 series CPU.

E pin of 68 series CPU shall be connected to this pin,

while RD pin shall be connected to this pin in the case of

80 series CPU.

The address bus of CPU shall be connected to these pins.

Instruction code is set by these pins.

The data bus of CPU shall be connected to these pins. These

pins are used to set the data of the instruction or to read

the data.

Test pins. Normally these pins should be set at VSS or

open.

Voltage supply pins. VDD is also used for the common

bias voltage level to drive the LCD.

Common bias voltage input pins to drive the LCD

Serial data output pin for SEGMENT drivers

Clock pulse output pin. The clock output from this pin

enables the character pattern data, which is output from

DO, to input to the SEGMENT drivers (MSM5839C or MSM5259).

Load signal output pin. The character pattern data to

the SEGMENT drivers, which was output from DO and

CP, is loaded to the LCD output of the SEGMENT

drivers, synchronized with the COMMON signal.

B-type AC signal output pin to drive the LCD

COMMON signal output pins to drive the LCD

This pin shows the internal condition of MSM6262-xx.

"H" shows that MSM6262-xx is in internal operation,

while "L" shows that MSM6262-xx is ready to receive

the instruction from the CPU.

This pin shows that MSM6262-xx is in internal operation

based on the instruction from the CPU, or MSM6262-xx

is in display revising operation based on the instruction

from the CPU.

"H" shows that MSM6262-xx is in internal operation,

while "L" shows that the display on the LCD has been

established and the MSM6262-xx is ready to receive an

instruction.
