SetFeature request in SX2
Who handles the SetFeature request in SX2? How does the SX2 support the test modes for electrical compliance testing as defined in section 7.1.20 of the USB 2.0 specification?
The SetFeature request will be handled by the SIE in CY7C68001. You need to ensure that the SX2 is enumerated successfully by the external master. The EZ-USB SX2 is an SIE-only device. A master is required to tell SX2 to connect. SX2 is intended to be used in self-powered mode. Therefore, when the diagnostic driver is loaded by the operating system to run the test suite, the SX2 should still be running and be ready to test.
