1. Bulkloop example uses total four endpoints.



Endpoints 2 and 4 are configured as BULK OUT endpoints.



Endpoints 6 and 8 are configured as BULK IN endpoints.

2. Data is looped back from endpoint 2 to 6 and 4 to 8.

Following snapshot shows you the transfer of 10 bytes data to Endpoint 2 using the CyConsole. “Bulk Trans” button available

on CyConsole is used to perform bulk or interrupt data transfer on selected pipe.

The data transferred to EP2 is as follows: 1 2 3 4 5 6 7 8 9 10

You can observe the Bulk OUT tranfer getting sucessful in the message window of CyConsole.
