F. STAND-BY MODE

(Turning off all display-lights and stopped oscillation function)

This mode turns off all display-lights (fixing COM at “Low”) and stops oscillation function.

This completely stops the internal operation of the PT6301 and attains low power consumption of VDD and VDISP.

Note: If the RESET signal is input while the stand-by mode in progress, the stand-by mode is released and all states are

initialized.

RELEASING THE STAND-BY MODE

The timing to release the stand-by mode is shown below.

The stand-by mode is released at the falling edge of CS. (The internal oscillation starts)

When the oscillation becomes stable, the data input is enabled. (Return CS to “High” before entering data)

After the stand-by mode is released, all display-lights are turned off. Release the all display-lights OFF mode to turn on

the display-lights.
