8 COMMAND PROTOCOL CONFIGURATION
General Information About The Command Protocol
I2C protocol :
CD_module & mmdsp are using an I2C protocol to communicate : CD_module is master of the I2C protocol,
and can access (in read and write mode) host registers of the STA016A to write commands to the mmdsp and
to read request from the mmdsp. It must use following I2C syntax :
device_address, host_register_number, host_register_value
where :
for a write acces, device_address is 0x86.
for a read acces, device_address is 0x87.
Writing a command to mmdsp :
CD_module write its command inside dedicated host registers (mainly H64 to H69), then it must signals the writ-
ing of this command to mmdsp by sending the interrupt IT_CMD to the core of mmdsp.
Note that IT_CMD is generated by cd_module threw a falling edge on the input line number 0 of the STA016A
