5.82 Port Error Detect CSR n (SPn_ERR_DET)
SRIO Registers
Each of the four ports is supported by a register of this type (see Table 158 ). The port error detect CSR n
(SPn_ERR_DET) is shown in Figure 145 and described in Table 159 .

Table 159. Port Error Detect CSR n (SPn_ERR_DET) Field Descriptions
Bit Field Value Description
31 ERR_IMP_SPECIFIC Implementation-specific error. This bit covers errors that are a result of
an illegal field in a maintenance packet, an illegal destination ID, and
an unsupported transaction.
0 An implementation specific error has not been detected.
1 An implementation specific error has been detected.
30–23 Reserved 0 These read-only bits return 0s when read.
22 CORRUPT_CNTL_SYM Bad CRC in control symbol
0 The port did not receive a control symbol with a bad CRC value.
1 The port received a control symbol with a bad CRC value.
21 CNTL_SYM_UNEXPECTED_ACKID Unexpected ackID in control symbol
0 The port did not receive an acknowledge control symbol with an
unexpected ackID (packet-accepted or packet-retry).
1 The port received an acknowledge control symbol with an unexpected
ackID (packet-accepted or packet-retry). The capture registers do not
have valid information during this error detection.
