Processor Idle Detection
In this mode, any changes in the CAS value in either direction will cause an entry
to be written to the FIFO if Processor Idle detection is enabled for this line. Note
that for a CAS change to be valid, it has to be stable for two consecutive
samples. Any additional filtering must be done in the external framers.
