Handshake Procedure
SSCNET board is composed of a DSP and other control units on
it. The DSP is a microprocessor for managing all devices on the
board. Once the CPU on host PC needs to communicate with
DSP, it must use dual port RAM on SSCNET board to do it. On the
same way, the DSP must communicate host CPU via dual port
RAM. The commander must check if he can send the command
and the responser must give him some ready signal for this proce-
dure. This is so called handshake. It takes time in handshake. The
handshake latency is 0.888ms because of the SSCNET protocol.
Some procedure needs a series of handshaking and they will be
introduced in the following sections.

Card Initial Procedure
The initial procedure is very complicated in SSCNET board. Once
the function “MDSP_initial()” is lauched, the following flow char will
be taken:
Step
Action
OK Reponse
Error Response
Error Reason
1
Power ON
LED Flash one by one and off
No LED Flashing or
LED always ON
ROM data corrupt. Please
download ROM data again.
Use Kernelupdate.exe to do it.
