However the PDMA can still access (read/write) the other OPRAM banks via the SW and NW controllers but such an access must be forwarded to those controllers meaning it has higher latency.</P><P>Best regards,</P><P>Gary</P> Wed, 18 Oct 2023 09:03:07 GMT https://community.nxp.com/t5/Other-NXP-Products/SPT3-1-OPRAM-about-pdma-command-bank/m-p/1741988#M19710 GaryRK 2023-10-18T09:03:07Z
