Critical Issue
Description
In DSP Builder version 13.1 and earlier, the RegFiled block may work only for one particular bus access type. Pipelined reads are not allowed, so you have to hold the data and address for the bus latency of the system number of cycles each time.
DSP Builder version 14.0 and later allows pipelined reads for the RegField bock. In addition, you can use any ModelBus block outside of GPIn, GPOut, ChannelIn, and ChannelOut blocks.
Resolution
To work around this problem and allow pipelined reads, upgrade to DSP Builder v14.0.
