We would like to tightly-couple a FPGA with a µC by means of the external static memory memory controller, thereby effectively mapping the FPGA registers into main memory of the µC with maximum bandwidth. At the moment we plan with 8-bit address & data and async. static NOR like interfacing.

For this setup it is necessary that each and every read/write is actually transmitted to the FPGA (memory) device and no buffering takes place. Since I am still new to the the LPC43xx family I wonder whether disabling buffers in the Static Memory Configuration registers is sufficient.
