Note (1): Default values depend on setting of LX4/CX4 select LX4_MODE pin. LX4 value is shown first. The value may be overwritten by the Auto-Configure operation
Note (1): These bits are latched low on any SIG_DET failure condition detected. They are reset high on being read.
Note (2): These bits are latched high on any LOS condition detected. They are reset low on being read.
Note (1): Default values depend on setting of LX4/CX4 select LX4_MODE pin. LX4 value is shown first. The value may be overwritten by the Auto-Configure operation
Note (2): The 0’h LX4 default value, combined with the 00’h pre-emphasis values (see Table 41) allow reduced power consumption in LX4 applications.
Note (1): This reset will NOT cause a reload of the NVR or DOM areas, nor an Auto-Configure operation. It will reset the Byte Sync engine, the Lane Alignment engine,
the FIFO pointers, and the I2C controller. The ISL35822 will (if “normally” configured) transmit ||LF|| local fault signals until Byte Sync and Lane Alignment are
re-established, and any DOM update in progress may be aborted.
