Transport Layer Feature Register
Table 6–51 describes the Rx Transport Control register. This register controls the
Transport layer mode.
Error Management Registers
Table 6–52 through Table 6–56 describe the error management registers. These
registers can be used by software to diagnose problems with packets that are received
by the local endpoint. If enabled, the detected error triggers the assertion of
sys_mnt_s_irq
. Information about the packet that caused the error is captured in the
capture registers. After an error condition is detected, the information is captured and
the capture registers are locked until the Error Detect CSR is cleared. Upon being
cleared, the capture registers are ready to capture a new packet that exhibits an error
condition.
Table 6–50. Input/Output Slave RapidIO Write Requests—Offset: 0x10510
Field Bits Access Function Default
RSRV [31:16] RO Reserved 16'h0
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.

Table 6–51. Rx Transport Control—Offset: 0x10600
Field Bits Access Function Default
RSRV [31:1] RO Reserved 31'h0
PROMISCUOUS_MODE [0] RW
This bit determines whether the Transport layer checks
destination IDs in incoming request packets, or
promiscuously accepts all incoming request packets
with a supported ftype.

Note to Table 6–51 :
(1) The default (reset) value is set in the RapidIO parameter editor for non-Arria 10 variations. The default (reset) value for Arria 10 variations is 1.
