ROAMING DECODER II

RSP:
Receiver Shutdown Packet enable. When this bit is set, a Receiver Shutdown Packet will be sent
whenever the receiver is shut down. The receiver shutdown packet informs the host that the
receiver shutdown, and how long it will be before the S5T8701 will automatically warm the receiver
back up. (value after reset=0)
SND:
Start Noise Detect. Setting this bit while the S5T8701 is battery saving will cause it to warm-up the
receiver, run a noise detect, and report the result of the noise detect via NDR in the Roaming Status
Packet. This bit is set by the host, and cleared by the S5T8701 once it has been processed. If the
time comes for the S5T8701 to warm up for automatically or the SAS bit is set while an SND is
being processed, the noise detect will be abandoned and the abandoned noise detect result
(NDR=01) will be sent in the Roaming Status Packet. (value after reset=0)
CND:
Continuous Noise Detect. Setting this bit will cause the S5T8701 to do continuous noise detects
during the decoded block data of a frame. The results of the noise detect will only be reported if
noise is detected (NDR=11).
Only one noise detected result (NDR=11) will be sent per block. If the S5T8701 has not completed
a noise detect when it shuts down for the frame, that noise detect will be abandoned, but no
abandon result (NDR=01) will be sent. This bit is set and cleared by the host. (value after reset=0)
RND:
Report Noise Detects. Setting this bit will cause the S5T8701 to report the results of the noise
detects it does under normal asynchronous operation (when first turned on and when
synchronous). The results of the noise detect will be reported via NDR in the Roaming Status
acket. This bit is set and cleared by the host. (value after reset=0)
ABI:
All Block Information words. When this bit is set, the S5T8701 will send all received Block
information words 2-4 to the host. Note: Setting the SBI bit in the Control Packet only enables
errored and real time clock related block info words. (value after reset=0)
SAS:
Start A-word Search. Setting this bit while in asynchronous battery save mode will cause the
S5T8701 to warm-up the receiver and run an A-word search. If, during the A-word search, the
S5T8701 finds sufficient FLEX signal, it will enter synchronous mode and start decoding the frame.
If the A-word search times-out without finding sufficient FLEX signal, it will battery save and
continue doing periodic noise detects. The time-out for the A-word searches is controlled by the
AST bits in the Timing Control Packet and the MOT bit in the Configuration Packet. The A-word
search takes priority over noise detects. Therefore, if the S5T8701 is performing an A-word search
and the time comes to do automatic noise detect, the noise detect will not be performed. This bit is
set by the host, and cleared by the S5T8701 once it has been acted on. (value after reset=0)
DAS:
Disable A-word Search. When this bit is set, an A-word search will not automatically occur after a
noise detect in asynchronous mode finds FLEX signal. This includes automatic noise detects and
noise detects initiated by the host by setting SND. The S5T8701 will shut down the receiver after
the noise detect completes regardless of the result. When this bit is cleared, A-word searches will
occur after a noise detect finds signal in asynchronous mode. (value after reset=0)
