Preliminary
8.5. Self ID
An example of software flowchart for receiving a self ID packet is shown in Figure 8.21. There is no context
program to receive self ID packets.
1) Clear LinkControl.rcvSelfID bit.
2) Set the host memory base address (in 2048- byte boundary) where the received packet is stored in the
selfIDBufferPointer register.
3) Set LinkControl.rcvSelfID bit.
4) Wait until the INTA# is set. (when IntMask.selfIDComplete bit)
5) Check the SelfIDCount.selfIDError bit.
