WRITE_OUT_OF_BOUNDS [1] RW1C
Write request address out of bounds. Asserted when the
Avalon-MM address does not fall within any enabled
address mapping windows.

READ_OUT_OF_BOUNDS [0] RW1C
Read request address out of bounds.
Asserted when the Avalon-MM address does not fall
within any enabled address mapping windows. 1'b0

Table 6–48. Input/Output Slave Pending NWRITE_R Transactions—Offset: 0x10508
Field Bits Access Function Default
RSRV [31:5] RO Reserved 27'h0
PENDING_NWRITE_RS [4:0] 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 8 Avalon
clock cycles after the start of the write burst on the
Avalon-MM interface.

Table 6–49. Input/Output Slave Avalon-MM Write Transactions—Offset: 0x1050C
Field Bits Access Function Default
RSRV [31:16] RO Reserved 16'h0
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_wr_write
and io_s_wr_chipselect signals are asserted and
the io_s_wr_waitrequest signal is not asserted.
This counter rolls over to 0 after its maximum value.
