  Provides an instruction, and optionally a memory or register operand,
  for use by a coprocessor (such as the 8087, 80287, or 80387). The first
  operand must be a 6-bit constant that specifies the bits of the copro-
  cessor instruction. The second operand can be either a register or mem-
  ory operand to be used by the coprocessor instruction. The CPU puts the
  specified information on the data bus where it can be accessed by the
  coprocessor. The assembler automatically inserts ESC instructions in
  coprocessor instructions.
