FUNCTION DESCRIPTION
OSCILLATION CIRCUIT
An oscillation circuit may be constructed by connecting external Resistor (R1) and Capacitor (C1) between the oscillator
pins -- OSCO and OSCI. The RC time constant depends on the value of VDD voltage used. The target oscillation
frequency is 2MHz. Please refer to the diagram below.
RESET FUNCTION
The Reset Function is enabled when the RSTB Pin is set to "Low" Level. All functions are initialized. The initial status of
the various functions is given below:
1. Address of each RAM: Address "00"H
2. Data of each RAM: All contents are undefined.
3. General Output Ports: All General Output Ports are set to "LOW".
4. Display Digit: 16 Digits
5. Contrast Adjustment: 8/16
6. All Display Lights: OFF Mode
7. Segment Output: All Segment Outputs are set to "LOW".
8. AD Output: All AD Outputs are set to "LOW".
The RSTB Pin may be connected to either the microcontroller or an external Resistor and capacitor. For an external RC
connection, please refer to the diagram below.

DATA TRANSFER
The Display Control Command and the data are written by an 8-bit serial data transfer. Please refer to the Write Timing
Diagram below.
Note: When data is written into the RAM (DCRAM, ADRAM, CGRAM) in a continuous manner, the address are automatically incremented. Therefore
it is not necessary to specify the first byte of the 2nd and later bytes when writing the RAM data.
When the CSB pin is set to "LOW" Level, data transfer operation is enabled. 8 bits of data are sequentially inputted into
the DIN Pin (LSB first). The shift clock is inputted into CLKB pin and the shift register reads the data at rising edge of the
shift clock. The internal load signals are automatically generated and the data is written to each register and RAM. Thus,
it is not necessary to input load signals externally.
When the CSB Pin is set to "HIGH" Level, the data transfer operation is disabled. The data input when the CSB Pin
changes from "HIGH" to "LOW" is recognized in 8-bit units.

COMMANDS
The following are the list of commands issued by PT6302. When data is written into the RAM (DCRAM, CGRAM, or

DATA CONTROL RAM (DCRAM) DATA WRITE COMMAND
The DCRAM Data Write Command is used to specify the address of the DCRAM and writes the character code of the
CGROM and CGRAM. The DCRAM consists of 4 address bits which are used to store the CGRAM & CGROM character
codes. The character codes specified by the DCRAM is converted to a 5 x 7 dot matrix character pattern via the CGROM
and CGRAM. The DCRAM can store up to 16 characters. The DCRAM Data Write Command Format is shown below.

GENERAL OUTPUT PORT SET COMMAND
The General Output Port Set Command is used to specify the general output port status. The general output port is used
to control other input/output devices as well as turn on the LED Display. When the general output port is set to "HIGH",
the output is equivalent to the VDD voltage. When the general output port is set to "LOW" Level, the output becomes
ground potential. The command format is given below.

DISPLAY DUTY SET COMMAND
The Display Duty Set Command is used to write the display duty value to the duty cycle register. Using a 3-bit data, the
display duty adjusts the contrast in 8 stages. When the power is turned ON or when the RSTB signal is inputted, the duty
cycle register value is set to "0". It is advisable to always execute this command before turning on the display, after which
the desired duty value may be set. The command format is given below.

NUMBER OF DIGITS SET COMMAND
The Number of Digits Set Command is used to write the number of display digits into the display digit register. Using a
3-bit data, the Number of Digits Set Command can display 9 to 16 digits. When the power is turned ON or when the
RSTB signal is inputted, the value is set to "0". It is advisable to always execute this command before the turning on the
display. The command format is given below.

DISPLAY LIGHT SET COMMAND
The Display Light Set Command is used to turn all display lights ON or OFF. All Display Lights ON Mode is primarily
used for testing the display. The All Display Light OFF Mode is used for the blinking display and to prevent any
malfunction when the power is turned ON. The general output port cannot be controlled by this command. The command
