How do I simulate an USB interrupt in Keil for the cypress fx2lp chip? Depending on the various usb interrupts that occur, the chip autovectors to that particular ISR. I want to test it by simulating. Is it possible at all in keil?
Also, in cypress's USBjmptb.a51, what does USB_Int2AutoVector equ $ + 2 mean?
The Device Database entry for each chip tells you what features are supported in simulation:
