Note:
If HS_CH_SYNC_HYSTERESIS[1:0] is equal to 2'b00), machine
operates as drawn.
If HS_CH_SYNC_HYSTERESIS[1:0] is equal to 2'b01/2'b10/2'b11,
then a transition from all Sync Acquired states occurs immediately
upon detection of 1, 2, or 3 adjacent invalid code words or
disparity errors respectively.
