AT7911E connected with the TSS901E (or SMCS332)
The new ECSS-E-50-12A SpaceWire standard, used by the AT7911E and the IEEE-1355 stan-
dard used by the old TSS901E are compatible, however the TSS901E has a slightly different
startup behavior, the TSS901E must be started first on a link connecting with the AT7911E.

AT7911E differences with the TSS901E (or SMCS332)
A few differences between the AT7911E and the TSS901E exist in the registers and in the
pinout. These differences are detailed in the section 14 of the ‘SMCS332SpW User Manual”.
Handling empty packets
An anomaly due to the SpaceWire codec implemented in the AT7911E affect the behavior of the
AT7911E when receiving empty packets. The description of this anomaly and the possible
workaround are given in the section 12 of the ‘SMCS332SpW User Manual”.
