12.3.4 Endpoint initialization
Table 15.
Each programmable buffer memory can independently be configured by using its ECR,
but the total physical size of all enabled endpoints (IN plus OUT) must not exceed
2462 bytes.
Table 16
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 16.
In response to standard USB request Set Interface, firmware must program all the 16
ECRs of the Peripheral Controller in sequence (see
enabled or not. The hardware then automatically allocates the buffer memory 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.
