SECTION 5
FLOATING POINT INSTRUCTIONS
This section contains information about the floating-point instructions for the MC68881,
MC68882, and MC68040. In this section, all references to the MC68040 do not include the
MC68LC040 and MC68EC040. Each instruction is described in detail, and the instruction
descriptions are arranged in alphabetical order by instruction mnemonic.
All floating-point instructions apply to the MC68881 and MC68882 processors. The
MC68040 directly supports part of the floating-point instructions through hardware. It
indirectly supports the remainder by providing special traps and/or stack frames for the
unimplemented instructions and data types. The following identification is noted under the
instruction title for the MC68040:
For all MC68040 floating-point instructions, the coprocessor ID field must be 001.
Table 5-1 lists the floating-point instructions directly supported by the MC68040, and Table
5-2 lists the floating-point instructions indirectly supported.
