Hi,
I would like clarification on the TRM statement "required accesses", i.e how it affects the case of residue words that does not fill a complete burst.
7.1.3.3.10.5 System Burst Versus External Device Burst Support
“When the system burst request length is less than the ATTACHEDDEVICEPAGELENGTH value, the GPMC proceeds with the required accesses.”
1- If I have setup the GPMC to run NOR Synchronous 4x 16bit word write bursts, then launch a write from DMA as 10x 16bit words to the memory, what access mode will the GPMC switch to for the last two words?
2- What timing penalty occurs (bus turn-around time)?
Thanks.
