MMDSP write its request inside dedicated host registers (mainly H70 to H78 and H134 to H169), then it signals
to cd_module that it must read a request by sending the interrupt IT_REQ.
Note that IT_REQ interrupt is generated by mmdsp on the IRQB pin of STA016A.
Note also that once it has finished to read the message, cd_module must always acknowledge it by reading
H10.
Reading a request from mmdsp :
