11.7.1.2
The Cache Type register is accessed by reading the register 0 with the opcode_2 field set to 1.
The Cache Type register contains information about the size and architecture of the caches.
• ISize[11:0]: Instruction Cache Size
Indicates the size, line length and associativity of the instruction cache.
• DSize[23:12]: Data Cache Size
Indicates the size, line length and associativity of the data cache.
• S[24]: Cache
Indicates if the cache is unified or has separate instruction and data caches.
Set to 1, this field indicates separate Instruction and Data caches.
• ctype[28:25]: Cache Type
Defines the cache type.
For details on bits DSize and ISize, refer to the ARM920T Technical Reference Manual, Rev. DDI0151C.
