6.3.6.10. Port 0 Error Detect

Table 162.  Port 0 Error Detect CSR — Offset: 0x340
Field Bits Access Function Default
RSRV [31] RO Reserved for this implementation. 1'b0
RSRV [30:24] RO Reserved. 7'h0
RSRV [23] RO Reserved for this implementation. The RapidIO II IP core does not support the Parallel RapidIO protocol. 1'b0
Received corrupt control symbol [22] RW Received a control symbol with a bad CRC value. 1'b0
Received ACK control symbol with unexpected ackID [21] RW Received a packet-accepted or packet-retry control symbol with an unexpected ackID. 1'b0
Received packet-not-accepted control symbol [20] RW Received a packet-not-accepted control symbol. 1'b0
Received packet with unexpected ackID [19] RW Received a packet with an unexpected ackID value — an out-of-sequence ackID. 1'b0
Received packet with bad CRC [18] RW Received a packet with a bad CRC value. 1'b0
Received packet exceeding max size [17] RW Received a packet that exceeds the maximum allowed size. For MAINTENANCE packets, the maximum allowed size is 78 bytes. For non-Maintenance packets, the maximum allowed size is 276 bytes. 1'b0
Received illegal or invalid character [16] RW Received an 8B10B code group that is invalid (has no decode with the current running disparity) or illegal (valid code group not allowed by the RapidIO protocol), When this bit is set, bit [2], Delineation error, is also set. 1'b0
Received data character in IDLE1 sequence [15] RW Reserved for this implementation, The RapidIO II IP core does not support the IDLE1 sequence. 1'b0
Loss of descrambler synchronization [14] RW Loss of receiver descrambler synchronization while receiving scrambled control symbol and packet data. 1'b0
RSRV [13:6] RO Reserved. 7'h0
Non-outstanding ackID [5] RW Received a link-response control symbol with an ackID that is not outstanding. Only triggers if at least one ackID is outstanding. 1'b0
Protocol error [4] RW Received an unexpected control symbol. 1'b0
RSRV [3] RO Reserved for this implementation. 1'b0
Delineation error [2] RW Received an 8B10B code group that is invalid (has no decode with the current running disparity), or illegal (valid code group not allowed by the RapidIO protocol), or is in a disallowed position in the received code-group stream. In the first two cases, bit [16] is also set to the value of 1. 1'b0
Unsolicited ACK control symbol [1] RW Received an unexpected packet acknowledgement control symbol. 1'b0
Link timeout [0] RW Did not receive expected packet acknowledgement or link-response control symbol within the time-out interval specified in the VALUE field of the Port Link Time-Out Control CSR or the Port Response Time-Out Control CSR. 1'b0
