Hello
I'm developing an application on the Cypress CY7C68013 USB controller. How can I enable and manage the INT5 interrupt? In all my tries, when the interrupt occurs (falling edge on the pin), the firmware freezes. Which function does the code call when the interrupt occurs?
Thanks
"The problem is that the INT5 is not present in the standard 8051"
C51 supports it - Documneted here: http://www.keil.com/support/man/docs/c51/c51_le_interruptfuncs.htm
forget the table if you have just an elementary understanding of math
interrupt_number = (vector_address -3)/8
