6.3.5.4. I/O Slave Transactions and Requests

Table 150.  Input/Output Slave Pending NWRITE_R Transactions — Offset: 0x10508
Field Bits Access Function Default
RSRV [31:8] RO Reserved. 24'h0
PENDING_NWRITE_RS [7:0] RO Number of pending NWRITE_R write requests that have been initiated in the I/O Avalon-MM slave Logical layer module but have not yet completed. The value in this field might update only after a delay of 4 Avalon clock cycles after the start of the write burst on the Avalon-MM interface. 8'h00
Table 151.  Input/Output Slave Avalon-MM Write Transactions — Offset: 0x1050C
Field Bits Access Function Default
RSRV [31:16] RO Reserved. 16'h0000
STARTED_WRITES [15:0] RO Number of write transfers initiated on Avalon-MM Input/Output Slave port so far. Count increments on first system clock cycle in which the io_s_write signal is asserted and the io_s_wr_waitrequest signal is not asserted. This counter rolls over to 0 after its maximum value. 16'h0000
Table 152.  Input/Output Slave RapidIO Write Requests — Offset: 0x10510
Field Bits Access Function Default
RSRV [31:16] RO Reserved. 16'h0000
COMPLETED_OR_CANCELLED_WRITES [15:0] RO Number of write-request packets transferred from the Avalon-MM Input/Output Slave module to the Transport layer or cancelled. Count increments when the write-request packet is sent to the Transport layer, or when a write transaction is cancelled. This counter rolls over to 0 after its maximum value. 16'h0000
