Product data
Remark: Register changes that affect the allocation of the shared FIFO storage
among endpoints must not be made while valid data is present in any FIFO of the
enabled endpoints. Such changes will render all FIFO contents undefined.
Table 67:
Each programmable FIFO can be configured independently via its ECR, but the total
physical size of all enabled endpoints (IN plus OUT) must not exceed 2462 bytes
(512 bytes for non-isochronous FIFOs).
Table 68
of 2462 bytes. The total number of logical bytes in the example is 1311. The physical
storage capacity used for double buffering is managed by the device hardware and is
transparent to the user.
