Transparent Mode (default after reset): This mode allows complete transparent data
transfer between two nodes without performing any interpretation of the databytes and
without generating any acknowledges. It is completely up to the host CPU to interpret the
received data and to generate acknowledges if required.
The TSS901E accepts EOP1 and EOP2 control tokens as packet delimiters and generates
autonomously EOP1/EOP2 (as configured) markers after each end of a transmission
packet.
This mode also includes as a special submode:
–
Simple Interprocessor Communication (SIC) Protocol Mode: This mode executes the simple
interprocessor communication protocol as described in the protocol specification
following capabilities of the protocol are implemented into the TSS901E:
–
–
–
In transmit direction no interpretation of the data is performed. This means that for transmit
packets, the four header bytes must be generated by the host CPU and must be available as
the first data read from the communication memory. EOP1/EOP2 control tokens are auto-
matically inserted by the TSS901E when one configured transfer from the communication
memory has finished.
Wormhole routing: This mode allows hardware routing of packets by the TSS901E.
