clearing ALOS_(n) in order to prevent chattering in
the RLOS_(n) output signal.
Monitoring the State of ALOS_(n)
If the XRT73L04A is operating in the HOST Mode,
the state of ALOS_(n) of Channel(n) can be polled or
monitored by reading in the contents of Command
Register CR0. .
COMMAND REGISTER CR0-(n)
If the ALOS_(n) bit-field contains a "1", then the cor-
responding Channel(n) is currently declaring an
ALOS condition. Conversely, if the ALOS_(n) bit-field
contains a "0", then the channel is not currently de-
claring an ALOS condition.
Disabling the ALOS Detector
For debugging purposes, it may be useful to disable
the ALOS Detector. If the XRT73L04A is operating in
the HOST Mode, disable the Channel(n) ALOS De-
tector by writing a "1" into the ALOSDIS_(n) bit-field
in Command Register CR2.
2. The Digital LOS (DLOS) Declaration/Clearance
Criteria
A given channel(n) declares a Digital LOS
(DLOS_(n)) condition if the XRT73L04A detects
160±32 or more consecutive "0’s" in the incoming da-
ta.
The channel clears DLOS if it detects four consecu-
tive sets of 32 bit-periods, each of which contains at
least 10 "1’s" (e.g., average pulse density of greater
than 33%).
Monitoring the State of DLOS
If the XRT73L04A is operating in the HOST Mode the
state of DLOS_(n) of Channel(n) can be polled or
monitored by reading in the contents of Command
Register CR0.
If the DLOS_(n) bit-field contains a “1”, then the cor-
responding channel(n) is currently declaring a DLOS
condition. If the DLOS_(n) bit-field contains a “0”,
then the channel(n) is currently declaring the DLOS
condition.
Disabling the DLOS Detector
For debugging purposes, it is useful to disable the
DLOS_(n) detector. If the XRT73L04A is operating in
the HOST Mode, the DLOS Detector can be disabled
by writing a “1” into the DLOSDIS_(n) bit-field in Com-
mand Register CR2.
