HDS2 Emulator phantom interrupt problem
2003-11-19 08:51 AM
Hi Everyone,
I am currently using the HDS2 emulator to emulate the ST72T511R9. When I enable interrupts in my software, a phantom interrupt is immediately generated - at vector location FFE0-FFE1. The data sheet tells me that this is a PWM-ART overflow interrupt. This occurs even though the interrupt is disabled in the ARTCSR (PWM control status reg). To be sure, inside the interrupt I read ARTCSR and then clear it again. The interrupt is continuously re-entered and I can't seem to stop it!! Any ideas anyone? Thanks in advance.
