9.3 Endpoint initialization
Table 5.
Each programmable FIFO can independently be configured through its ECR. The total
physical size of all enabled endpoints (IN plus OUT), however, 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 device hardware and is transparent
to the user.
Table 6.
In response to standard USB request Set Interface, firmware must program all 16 ECRs
of the ISP1183 in sequence (see
hardware will then automatically allocate FIFO storage space.
If all endpoints have successfully been configured, firmware must return an empty packet
to the control IN endpoint to acknowledge success to the host. If there are errors in the
endpoint configuration, firmware must stall the control IN endpoint.
