| ? | | 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). | ||

If "special segment" flag is set, 0x214 bytes are read from [[CfgS:GetConfigInfoBlk8]] block 0x70000, and then copied to the special segment given. If the reading fails, zeroes are written in its place. The purpose of this segment is currently unknown. | |||
