15. R4000 Processor Interrupts
15.1 Hardware Interrupts
The six CPU hardware interrupts can be caused by external write requests to the R4000SC, R4000MC, and R4000PC, or can be caused through dedicated interrupt pins. These pins are latched into an internal register by the rising edge of SClock. The R4000MC and R4000SC packages support a single interrupt pin, Int*(0). The R4000PC package supports six interrupt pins, Int*(5:0).
