Product data
Table 5:
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.
Table 6
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 peripheral hardware
and is transparent to the user.
