Save the supported CSW.Size data types for the MEM-AP. Each bit corresponds to a data type. 0b1 = Supported data size. 0b0 = Not supported. Bit 0 = Byte (8-bits) Bit 1 = Halfword (16-bits) Bit 2 = Word (32-bits) - always supported by spec. Bit 3 = Doubleword (64-bits) Bit 4 = 128-bits Bit 5 = 256-bits
