DP83822IF: the link status of DP83822IF working in 100M-FX mode

Part Number: DP83822IF

Hi Ti experts,

      Previous ,we have used DP83822IF in100M-TX mode , the function is OK.  now , we are using DP83822IF in 100M-FX mode,  there is a packet loss in first few packet,  then I read the link status of register 0x0001(bit 2), 0x08 is the PHY address of one port, before I read it,the fiber connection is OK, the first value is 0x7849, that is to say, the link is not eatablished, but after the first time I read it, the link status is OK ,

I don't know why the first link status is abnormal?  thanks for your help
