DS90UB954-Q1: How to set the Parity error threshould

Part Number: DS90UB954-Q1

Hi team,

Could you tell me correct setting to the parity error threshold.

If we want to set RX_PORT_STS1.PARITY_ERR to 1 when it is detected only one Parity error, should we set PAR_ERR_THOLD to 0 or 1?

Best regards,

Tomoaki Yoshida

    Hello Yoshida-san,

    You should set the threshold to 1.

    Please see the description for Table 7.6.6 and 7.6.7 in he 954 datasheet: "For each port, if the FPD-Link III receiver detects a number of parity errors greater than or equal to total value in PAR_ERR_THOLD[15:0], the PARITY_ERROR flag is set in the RX_PORT_STS1 register."

    Regards,
