The number of consecutive identical digits before digital LOS is asserted.
Assert threshold in bits = (TxdLosAssertThresh x 5 + 2) x 1024. See Figure 10 on
page 19.
D6
D6
Clear threshold that releases a digital LOS event.
The number of consecutive 1024 bit fields with at least one transition that are
required to clear dLos is calculated as RxdLos clearthresh x 16 + 1. See
Figure 11 on page 20.
