Hi,

I want to programm Flash of ST7FLite29 by ST7STICK. I don't know if I had to use a pull-up or a pulldown resistor on pin: ICCCLK and ICCDATA. Margel

Hello,

You can leave them unconnected on the application board but if you don't want to leave them floating in your application board, pull them up. ICCCLK pin must never be connected to an external pull-down because a/ to avoid entering ICC mode during an application reset. b/ you must be sure that the driver tool is able to supply enough power to keep high level on those pins. STICK manual says that for both ICCCLK and ICCDATA, application board must not drive more than 1mA of current.
