Hi,

You may enable the retimer to issue interrupt based on PRBS checker errors by setting channel register 0x31[7]=1. The channel registers write routine for enabling PRBS checker is included below.

Table. Register Writes to Enable PRBS Checker

STEP	SHARED/ CHANNEL REGISTER SET	OPERATION	REGISTER ADDRESS [HEX]	REGISTER VALUE [HEX]	WRITE MASK [HEX]	COMMENT
1	Channel	Write	0D	00	80	Turn on the de-serializer
2	Channel	Write	79	40	40	Set prbs_chkr_en=1
3	Channel	Write	30	00	08	Set prbs_en_dig_clk=0 to disable the digital clock
4	Channel	Write	30	08	08	Set prbs_en_dig_clk=1 to enable the digital clock
5	Channel	Write	30	10	10	Force reload of PRBS checker seed
6	Channel	Write	30	00	10	Undo force reload of PRBS checker seed
7	Channel	Write	82	40	40	Reset PRBS counters
8	Channel	Write	82	00	40	Un-reset PRBS counters
9	Channel	Read	01			Read PRBS status: Reg_0x01[6]: PRBS pattern polarity detection 1’b0: Polarity detected is not inverted 1’b1: Polarity detected is inverted Reg_0x01[4]: PRBS sequence detected 1’b1: Pattern detected 1’b0: No pattern detected Reg_0x01[3:1]: PRBS detect result 3’b000: PRBS7 3’b001: PRBS9 3’b010: PRBS11 3’b011: PRBS15 3’b100: PRBS23 3’b101: PRBS31 3’b110: PRBS58 3’b111: PRBS63
