Why cant I see the operand data in my 5307 trace?
(Assuming you have requested operand data in the trace: see Trace Control Options) On the 5307 any operand data which is sourced or sinked to the on-chip cache does not get written to the DDATA pins. If you must see the operand data in the trace your only option is to disable the cache operation for the required data area. This can usually be done by programming the ACR0 or ACR1 registers to specifically exclude cache operations on a specified memory area.
