Short Description	Interrupts that can override DMA

 bit 7 = NMI
 bit 1 = Line
 bit 0 = ULA

• Set bits indicate the corresponding interrupt will interrupt a dma operation when in hw im2 mode

Soft reset = 0x00

Because interrupts are only sampled at the end of an instruction by the Z80, each time the dma is interrupted one instruction of progress is made in the main program.
