SNLS696A April 2021 – May 2021 TSER953
The TSER953 monitors the status of the back channel link. The back channel CRC errors are reported in the CRC_ERR bit (Register 0x52). The number of CRC errors are stored in the CRC error counters and reported in the CRC_ERR_CNT1 (Register 0x55) and CRC_ERR_CNT2 (Register 0x56) registers. The CRC error counters are reset by setting the CRC_ERR_CLR (Register 0x49) to 1.
When running the BIST function, the TSER953 reports if a BIST CRC error is detected in the BIST_CRC_ERR bit (Register 0x52). The number of BIST errors are reported in the BIST_ERR_CNT field (Register 0x54). The BIST CRC error counter is reset by setting the BIST_CRC_ERR_CLR (Register 0x49) to 1.
