Forum Post: RE: C64+ Atomic Interrupt

Hi Geir, Are you building a SYS/BIOS (BIOS 6) or DSP/BIOS (BIOS 5) application ? I am guessing in order to register an interrupt for intNum 15, you are creating a Hwi ? When do you see the interrupt mask being set to all ? If you create an interrupt with disableMask set to all, then when this interrupt is serviced, it will disable all other interrupts (basically not allow nesting). The other interrupts will not be lost though. They will get executed once this interrupt is finished. Best, Ashish
