Question about ADSP-21479 ROM


I am planning on using the ADSP-21479 for digital filtering and have a large number of filter coefficients that I will need to store. I am trying to determine if I would be able to store them in Block 0 or Block 1 ROM. I've checked the datasheet and it just says that the ROM is not reserved on some models, but doesn't specify which ones.

If anyone could clarify whether or not I could store my coefficients in ROM or if I will need to use the SRAM instead I would appreciate it, thanks.
