DMA transfer to a gpio data register
I'm playing around with a psoc4m pioneer kit, and I'm trying to initiate a dma transfer from a buffer to a gpio port data register (CYREG_GPIO_PRT0_DR). I couldn't find any documentation specifically saying this won't work, but I haven't had any luck so far. If I'm not using DMA, I can write directly to the port register no problem. Any thoughts? Thanks.
