The DMA can only reach the "normal" physical address of the GPIOs, but cannot do bit-banding.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:04:12 GMT https://community.nxp.com/t5/LPC-Microcontrollers/write-to-bit-band-alias-using-gpdma/m-p/523960#M6596 lpcware 2016-06-15T18:04:12Z Re: write to bit band alias using gpdma https://community.nxp.com/t5/LPC-Microcontrollers/write-to-bit-band-alias-using-gpdma/m-p/523961#M6597 <HTML><HEAD></HEAD><BODY><P>This would be super useful to have in the documentation.
