In IPUG48 (LatticeSCM Ethernet FLexiMAC USER GUIDE) what does the rb_flt_stt bus mean exactly?

In 10 GbE mode, the rb_flt_stt[1:0] bus indicates whether NO FAULT, a LOCAL FAULT or a REMOTE FAULT is received from the RX PCS DATA, as described in Table 46-5, section 46.3.4 Link fault signaling of the IEEE 802.3ae -2002 specification and the following table.



































Lane 0Lane 1Lane 2Lane 3FAULT Description
Sequence0x000x000x00Reserved
Sequence0x000x000x01Local Fault
Sequence0x000x000x02Remote Fault
Sequence0x000x000x03Reserved


NOTE: Sequence= 0x9C with Kctrl=1

You cannot disablerb_flt_stt[1:0] . bit 1 of SMI memory 0x0f (smi_rsl_dis) when set to 1 will not disable rb_flt_stt[1:0] signaling.
