#100388 - TI MSC121x? Responding to: ???'s previous message |
As others have said, you really need to tell us what microcontroller you're using. You could be using literally any one of hundreds of 8052-compatible derivatives.
That said, I think I recognize those routines as being from the TI MSC121x ROM code. If that is the case, you must disable interrupts before executing code that will modify flash memory. With the TI parts, you cannot run code from flash memory when flash memory is being written to. The serial interrupt is going to jump to 0023h which is in flash memory and that's going to create your conflict. Regards, Craig Steiner |
