The OUT endpoint is programmed to all ACK and NYET interrupts as shown in
Next is the initialization of the Interrupt Enable register (see
respective bit to logic 1 enables the interrupt signal to be generated on the INT pin of the
ISP1582/83. Take into consideration the Interrupt Service Routine (ISR) because an
AND operation must be performed on the bits in the Interrupt register with the Interrupt
Enable register. The Interrupt register reflects the status bit of the respective event, even
if the enable bit is not set in the Interrupt Enable register.
