Fast-comparison DAC threshold adjust for high LOS. The combination of HLOS and LLOS creates a hysteresis
comparator. As RSSI falls below the LLOS threshold, the LOS LO alarm bit is set to 1. The LOS alarm remains set
until the RSSI input is found above the HLOS threshold setting, which clears the LOS LO alarm bit and sets the
LOS HI alarm bit. At power-on, both LOS LO and LOS HI alarm bits are 0 and the hysteresis comparator uses the
LLOS threshold setting.
