Main endpoint
The main endpoint (endpoint number 2) is the primary endpoint for sinking or
sourcing relatively large amounts of data. It implements the following features to ease
this task:
Double buffering. This allows parallel operation between USB access and local
CPU access thus increasing throughput. Buffer switching is handled automatically.
This results in transparent buffer operation.
DMA (Direct Memory Access) operation. This can be interleaved with normal I/O
operation to other endpoints.
Automatic pointer handling during DMA operation. No local CPU intervention is
necessary when ‘crossing’ the buffer boundary.
Configurable endpoint for either isochronous transfer or non-isochronous (bulk and
interrupt) transfer.
