4.5.3.3.1. Keeping Track of I/O Write Transactions
The following three registers are available to software to keep track of I/O write transactions:
- The Input/Output Slave Avalon® -MM Write Transactions register holds a count of the write transactions that have been initiated on the write Avalon® -MM slave interface.
- The Input/Output Slave RapidIO Write Requests register holds a count of the RapidIO write request packets that have been transferred to the Transport layer.
- The Input/Output Slave Pending NWRITE_R Transactions register holds a count of the NWRITE_R requests that have been issued but have not yet completed.
In addition, the NWRITE_RS_COMPLETED bit of the Input/Output Slave Interrupt Enable register controls a maskable interrupt in the Input/Output Slave Interrupt register that can be generated when the final pending NWRITE_R transaction completes.
You can use these registers to determine if a specific I/O write transaction has been issued or if a response has been received for any or all issued NWRITE_R requests.
