The following example presents the structure of descriptors to issue the ReadDMA command:
19-42
9. Initialize the CQPMP register with the device’s PM number. If the port multiplier is not used, clear
10. Poll the CQR[CQn] to determine which command can be issued.
11. After CQn is determined, write 1 to CQR[CQn] to issue this command and start execution.
12. Poll the CCR[CCn] till CCn goes up, indicating that the command is completed.
