This eight-bit register works in conjunction with the LOSFLT register to provide hysteresis and control the operation of the loss of
signal comparator. The comparator’s output, RXLOS, is asserted when the input on VRX falls below the level in LOSFLT. The
output will then be de-asserted when the VRX signal rises above the level in LOSFLTn.
The input signal is subject to scaling by the RXPOT. If the LOS comparator is disabled, i.e., LOSDIS = 1, this register is ignored.
A valid OEM password is required for access to this register. This register is non-volatile and will be maintained through power
and reset cycles.
