6.3.3 Lane Event Notification
In order for lane errors to trigger any event notification function, the bit associated with the event(s) of interest must be enabled
in the
Lane {0..47} Error Report Enable Register .
Lane events can trigger interrupt or Standard port-write notification. To enable Standard port-write notification for Lane events,
the
Lane {0..47} Control Register .LANE_PW_EN bit must be set. Once this bit is set, lane events that are in the Lane {0..47}
Error Report Enable Register will cause a port-write to be sent.
To enable interrupt notification for any lane event, the Lane {0..47} Control Register .LANE_INT_EN bit must be set. Once this
bit is set, lane events that are enabled in Lane {0..47} Error Report Enable Register will cause the interrupt line to be asserted.
To enable Error Log reporting of all enabled lane events for a port, the Port {0..17} Operations Register .LANE_LOG_EN bit
must be set. Once this bit is set for all lanes assigned to that port, all lane events that are enabled in the Lane {0..47} Error
Report Enable Register will be reported to the Error Log. For more information on how the Error Log can assert interrupts and
send IDT port-writes, see Error Log Event Notification Programming Model .
6.3.4 I
2
C Event Notification
I
2
C events can trigger interrupt or Standard port-write notification. To enable Standard port-write notification for I
2
C events, the
I2C Master Control Register . I2C_PW_EN bit must be set. Once this bit is set, I
2
C events that are enabled as described in I2C
Events will cause a port-write to be sent.
To enable interrupt notification for any I
2
C event, the I2C Master Control Register .I2C_INT_EN bit must be set. Once this bit is
set, I
2
C events that are enabled as described in I2C Events will cause the interrupt line to be asserted.
To enable Error Log reporting of I
2
C events, the Aux Port Error Report Enable Register .I2C_LOG_EN bit must be set. Once
this bit is set, I
2
C events that are enabled as described in I2C Events will be reported to the Error Log. For more information on
how the Error Log can assert interrupts and send IDT port-writes, see Error Log Event Notification Programming Model .
