Table 3-10
The remainder of this section describes in detail each of the individual MaverickCrunch
instructions. The fields in the opcode for each MaverickCrunch instruction are shown. When
specific bit values are required for the instruction, they are shown as either '1' or '0'. Any field
whose value may vary, such as a register index, is named as in the ARM programming
manuals, and its function described below.
