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.
