Hi,
In the datasheet of DP83822IF, under Pin Functions, it is mentioned as default Mode of LED_0 is Mode 1and in this mode ,LED indicates the status of the link. When the link is good, LED is ON. When the link is down, LED is OFF.
But in the bootstraps configuration table, it is given that the default mode for LED_0 is Mode 4. Since it have internal pull- up , I believe that this data is correct and mode 1 mentioned in the Pin functions table is wrong. Please confirm.
Also please confirm that the behaviour of LED_0 in Mode 4 is like that LED will be ON for good link and OFF when the link is down.
