Cleared
Note:
* The Q dB is set in the LOS[4:0] bits.
** A hopping 128-bit window means this: An entire 128 bits is taken from the data stream and is checked. If the criteria are not met, all the 128 bits are thrown and another 128 bits are
caught for checking.
Detecte
Note:
* The Q dB is set in the LOS[4:0] bits.
** A hopping 32-bit window means this: An entire 32 bits is taken from the data stream and is checked. If the criteria are not met, all the 32 bits are thrown and another 32 bits are caught
for checking.
