DET_THR[3:0]:
DET_THR[3:0] references one of the threshold settings in Table 15 as the ALOS detection
criteria. If the equalised cable loss is greater than or equal to the threshold for N consecutive
pulse periods, where N = 16 * DET_PER stored in the RLPS ALOS Detection Period
Register, ALOS is declared and interrupt set.
CLR_THR[3:0]:
CLR_THR[3:0] references one of the threshold settings listed in Table 15 as the ALOS
clearance criteria. ALOS is cleared when the equalised cable loss is less than the threshold
for N consecutive pulse intervals, where N = 16 * CLR_PER stored in the RLPS ALOS
Clearance Period Register.
