Floating Point Instructions
FMOVECR
Instruction Fields:
5-84
The on-chip ROM contains other constants useful only to the on- chip microcode rou-
tines. The values contained at offsets other than those defined above are reserved for
the use of Motorola and may be different on various mask sets of the floating-point
coprocessor. These undefined values yield the value 0.0 in the M68040FPSP.
Coprocessor ID field—Specifies which coprocessor in the system is to execute this
Destination Register field—Specifies the destination floating- point data register.
ROM Offset field—Specifies the offset into the floating-point coprocessor on-chip
