Hi everybody.
I'm using SH7615. My board uses external interrupt with IRL3 to IRL0 pins, with IRL mode and Auto-Vector Mode Interrupts.
My hardware was setup IRL3: IRL0 = 0101 , that means always has external interrupt with Vector number = 69 and Piority level = 10
My question is how to disable this external interrupt in SH7615, I read datasheet but I couldn't find the register describe this problem?
Best regard.
Thanks for your idea. I will try it
I read datasheet SH in Interrupt section, but I didn't understand clearly about four bits interrupt request mask I3:I0 of Status Register when handles the interrupt routine.
I think when a interrupt source is accepted, its piority will be copied to I3:I0 of Status Register. After interrupt routine done, value in that 4 bits remain(Is that right? ) . I wonder that, when return to main program, and there is another interrupt that has its piority lower than I3:I0, what will happen? This Interrupt source will be accept or not? And how to clear I3:I0?
Thanks for your attention.
Best regard.
But after reset I3:I0 = 1111
So, when were they cleared to 0?
I understood clearly
Thanks for help
