AGSI : External Interrupt Simulation

Hi,

We are using Evatronix R80C51XC2 device in our ASIC and trying to simulate the external interrupts from our custom peripheral dll.

The chip is configured with 13 external interrupts. I understand that the dll should use "INTPINS" Virtual register to raise the interrupts. But, the size of the register is 8 bits how should we raise the 13 external interrupts.

Best regards,
Karthik

  • Some more info

    I was able to generate External interrupt 0 and 1 by writing 1 to INT0PIN and INT1PIN, but was not able to generate the external interrupt 0 to 13 by writing any value to INTPINS.

    However, the Pheripheral Simulation in Keil was able to generate all the external interrupts.
    I could not get this working from the Command window.

    Any help will be much appreciated.

    Best regards,
    Karthik
