These bits are two user-defined bits for operand accesses (see 4.2.2.3 Descriptor Field
Definitions ).
These bits are two user-defined bits for instruction prefetch bus cycles (see 4.2.2.3
Descriptor Field Definitions )
0 = The instruction ATC operates with 64 entries.
1 = The instruction ATC operates with 32 entries.
00 = Writethrough, cachable
01 = Copyback, cachable
10 = Cache-inhibited, precise exception model
11 = Cache-inhibited, imprecise exception model
0 = Reads and writes are allowed.
1 = Reads are allowed, writes cause a protection exception.
