66AK2G12: The purpose of USB0EXTTRIGGER pin (USB 2.0)

Part Number: 66AK2G12

What is the function of USB0EXTTRIGGER (H22) pin for USB 2.0?

The 66AK2G1x's Technical Reference Manual says that the description of USB0EXTTRIGGER is "External trigger for tracing data".

When do we use it? (Optional ? Essential?)

  • Hi, 

    That signal is not needed for a standard USB connection.  It is associated with a special emulation capability using USB.  

    Regards, Bill
