Hi,
I'd like to use CY7C65632/42 for the project.
I see there's LED control pins on CY7C65632/42 series
But I'm wondering -
1. What is the default control behaviour for GREEN/AMBER?
2. Can you control the LED behaviour?
3. How can you control, by pre-programmed into EEPROM? Or is it either one situation, once either choose EEPROM or LED function?
It's because we want to have LED indicator shows USB data transfer,
and I see there are LED control pins but I don't understand the description fully nor the exact LED control behaviour.
Could you kindly help to elaborate a bit more in detail?
Thanks,
Bertram

The port indicator behavior is specified by the USB specification as follows.
This table comes from the "Chapter 11 Hub Specification" of the "Universal Serial Bus Specification Revision 2.0" document.

Hi Bertram,
The AMBER and GREEN pins of the hub if 48-QFN package are present for either driving LEDs as Port indicators or Pin-strapping for configuration. They are by default active HIGH.
You could program the EEPROM with your custom descriptors or use Pin-strap configuration before enumeration.
Best Regards,
Sananya
