The sample signals FAR1S and FAR2S should be
asserted to fetch the 32 bits of FAR. CPDUS, FAR1S, FAR2S,
AUS1S and AU2S cannot be asserted simultaneously. If
CPDUS, FAR1S, FAR2S, AUS1S and AU2S are not asserted,
activating the TMC signal will generate invalid data on the
TMD output. If the FAR status report interface is not used, the
FAR1S and FAR2S signals should be connected to V
DD
.
Figure 14 describes the FAR telemetry serial interface.
Serial AU Status Interface in 5 Samples Mode
The 80 bit Authentication Unit Status report can be
retrieved through this interface. It is possible for an application
to use either a serial or a parallel interface to read out this
status report. The serial or parallel mode is selected with the
PAR configuration pin of the PTD (ee section 5.4). The serial
interface in 5 samples mode is implemented with 4 signal lines:
AU1S: first status sample input,
AU2S: second status sample input,
TMC: status clock input, is also used for CPDUS and
FAR.
TMD: status data output, is also used for CPDUS and
FAR.
When AU1S is asserted, the pointer for reading out data
with AU2S is reset to the second octet of the report. The
sample signals AU1S and AU2S should be asserted as
described in Figure 15 to fetch the 80 bits of AUS report.
CPDUS, FAR1S, FAR2S, AUS1S and AU2S cannot be
asserted simultaneously. If CPDUS, FAR1S, FAR2S, AUS1S
and AU2S are not asserted, activating the TMC signal will
generate invalid data on the TMD output. If the AU status
report interface is not used, the AU1S and AU2S signals
should be connected to V
DD
.
Figure 15 describes the AUS telemetry serial interface.
Serial CPDU, FAR, AU Status Interface in 2
Samples Mode
The 16 bit Command Pulse Distribution Unit status report,
the 32 bit Frame Analysis report and the 80 bit Authentication
Unit status report can be retrieved through this interface. The
serial interface in 2 samples mode is implemented with 4
signal lines:
CPDUS: first status sample input,
FAR1S: second status sample input,
TMC: status clock input,
TMD: status data output.
Note: The 0 bit is the MSB and is transmitted first.
