Checking Enumerated Speed of the CY7C68001 EZ-USB SX2.

Question: How to know if the CY7C68001 EZ-USB SX2 has enumerated at full- or high-speed?

 

Answer:

The external master has to check the HSGRANT bit after receiving the ENUMOK interrupt. If this bit is set, the SX2 has enumerated at high-speed.
