PSoC 3 Cut-through USB/DMA mode example?
I need to use the cut-through USB/DMA mode in my design. Is there any example or more detailed appnote available?
Background: I want to use two 512 byte ISO endpoints. The maximum endpoint buffer in the PsoC 3 is in total 512 byte so i can only use a 256 byte endpoint buffer per endpoint. By using cut-through USB mode, the PSoC 3 will only keep part of the endpoint data in the endpoint buffer such that up to 1023 byte endpoint buffers can be simulated. As data is being sent to the host, more data is being DMAed from RAM to the endpoint buffer. Very nice but very little documentation available.
