MaverickCrunch Co-Processor
EP93xx User’s Guide
3
co-processor uses this bit to distinguish between single precision floating point/32-bit
integer numbers (N=0) and double precision floating point/64-bit integer numbers (N=1).
W: Specifies whether or not a calculated address is written back to a base register (W=1)
or not (W=0). This bit is ignored by the MaverickCrunch co-processor.
offset: An 8-bit word offset used in address calculations. These bits are ignored by the
MaverickCrunch co-processor.
Table 3-6, Table 3-7, Table 3-8, and Table 3-9, define the bit values for opcode2, opcode1,
and cp_num for all of the MaverickCrunch instructions.
