what is cplb_miss_without_replacement exception for BF561?

Hi all,

I am using a custom BF561 board to debug a product and got the cplb_miss_without_replacement exception only when one option of the algorithm is enabled. This option requires a lookup table.

EXCAUSE in Sequencer status is 0x26 and HWERRCAUSE is 0x00.

I wasn't the original author of the project but found an interesting fact that the project is configured not to use external SDRAM memory even there are 32MB on board. :) In the Startup Code Settings in Project Options, Instruction cache memory is set Disable cache and enable memory protection and the Data cache memory is the same. Is it the root cause of cplb_miss_without_replacement exception?
btw, how do I locate the source code corresponding to RETI and RETX in the Sequencer register ?

Thanks.
