Errata
Specification Update
47
instruction pointer (LIP) is pointing to a floating-point instruction whose instruction
bytes are in UC space and which takes an exception 16 (floating point error
exception). The processor stalls trying to fetch the bytes of the faulting floating-point
instruction and those following it. This processor hang is caused by interactions
between thermal control circuit and floating-point event handler.
Implication:
The processor will go into a sleep state from which it fails to return.
Workaround:
Use a duty cycle other than 12.5% or 25%.
Status:
For the steppings affected, see the
Summary Tables of Changes.
