ST72681

Human interface implementation

15/32

Human interface implementation

6.1

LED behavior

The application is designed to manage 2 LEDs. This behavior is configurable through PC

dedicated software: ‘ST7268x Production Tool’.

By default, LED 1 responds to NAND access activity and LED 2 responds to USB activity.

Use of LED 1 is optional. When this option is not active, LED 2 reacts to both USB and

NAND activity.

6.2

Read only switch

The READ ONLY pin of the ST72681 is an input pin to be connected to VDD or GND

depending on the behavior of the device.

●

When this pin is connected to GND, no limitations are applied on the PC command

received.

●

When this pin is connected to VDD or unconnected, the firmware filters all accesses to

the NAND which modify the NAND state (write, erase, etc.) and returns an error to the

PC.
