| Communication ports? (bits 0-7: ???, 8-15: ???) (ever bit represents a memory region the region is always 0x8000 Byte in size (the first region starts at 0x1ff00000 the next is a 0x1ff08000 and so on) .The control port is (u8*)(0x1ec40000 + bit position (for bit 0 it is 0x1ec40000 for bit 15 it is 0x1ec4000F)).
| Memory layout (bits 0-7: Program ram, 8-15: Data ram). Each bit represents a memory region. The region is always 0x8000 bytes in size (the first region starts at 0x1FF00000; the next is a 0x1FF08000 and so on). The HW registers for DSP memory configuration are [[CONFIG11_Registers#CFG11_SHAREDWRAM_32K_DATA|CFG11_SHAREDWRAM_32K_DATA]] and [[CONFIG11_Registers#CFG11_SHAREDWRAM_32K_CODE|CFG11_SHAREDWRAM_32K_CODE]], located at physical address 0x10140000 (mapped to 0x1EC40000).
