register) to or from an effective address. A 32-bit transfer is always performed, even
though the system control register may not have 32 implemented bits. Unimplemented
bits of a control register are read as zeros and are ignored during writes (must be zero
for compatibility with future devices). For the MC68881, this instruction does not cause
pending exceptions (other than protocol violations) to be reported. Furthermore, a write
to the floating-point control register exception enable byte or the floating-point status
register exception status byte cannot generate a new exception, regardless of the
value written.
