Can I choose which counter my PL330 program uses?

Applies to: PL330 AXI DMA Controller

Answer

No - it is the assembler that decides. If counter 0 is free, the assembler will use it. If not, it will use counter 1 Consequently, it is possible to have two nested loops each interating over 255 cycles, i.e. a the equivalent of a sixteen-bit counter.
