How to access X-RAM/Y-RAM even if DSP unit is halted by module standby?

Latest Updated:03/23/2009

Question:

Is it possible to access the X-RAM/Y-RAM, even though the clock supply to the DSP unit is halted by the module standby function?

Answer:

It is possible to access the X-RAM/Y-RAM from the CPU or DMAC, even though the clock supply to the DSP unit is halted.

It is impossible to access the X-RAM/Y-RAM using DSP-type instructions (all instructions with a DSP Register, MACH or MACL as an operand).
