Threshold Settings Page
RECEIVED SIGNAL STRENGTH INDICATION (RSSI)
CR19<5:0>
These control bits are used to specify the RSSI threshold for
measuring and generating the energy detect (ED) signal.
When RSSI exceeds this threshold, ED is declared.
CLEAR CHANNEL ASSESSMENT TIMER CR17<7:0>
This control register is used to configure the period of the
time-out threshold of the CCA watchdog timer.
CLEAR CHANNEL ASSESSMENT CYCLE CR18<7:0>
This control register is used to configure how many times the
CCA timer is allowed to reach its maximum count before it
declares that the channel is clear (independent of the actual
energy measured in the channel).
ENABLE 1/4 CHIP ADJUST DURING ACQUISITION/DATA
CR5<6:6>
This control bit is used to enable/disable 1/4 chip timing
adjustments during acquisition or data.
ACTUAL CLEAR CHANNEL ASSESSMENT TIME
This indication-only field calculates the actual Clear Channel
Assessment Time Out interval (the inner loop).
RECEIVE BIT SYNC AMPLITUDE (ACQUISITION/DATA)
CR22<7:0> CR23<7:0>
These control registers are used to specify the bit sync
amplitude quality threshold used for acquisition and for data.
See typical values in the HSP3824 Datasheet.
RECEIVE PHASE VARIANCE (ACQUISITION/DATA)
CR30<7:0>
CR31<7:0>
These control registers are used to specify the phase
variance quality threshold used for acquisition and for data.
See typical values in the HSP3824 Datasheet (AnswerFAX
doc # 4064).
