When using the plb peripheral templates generated by Create and Import Peripheral Wizard, if the peripheral data width is less than 64 bit and includes user logic (ip) master module, the user logic (ip) master module might not work properly if burst support is turned off.
To work around this problem, you can either:
1. Turn on the burst support in the GUI.
2. Manually modify the peripheral HDL template file (DEV_BURST_ENABLE = 1) to enable burst support in PLB IPIF.
