DP83867IS: ANEG_SEL of strap function

K.Yaita

Part Number: DP83867IS

Hi Team,

I found ANEG_SEL (Auto-Negotiation Select) in strap configuration.

Is the configuration for ANEG_SEL no effect under Autoneg Disable=1 (MODE 4)?

Hello Yaita-san,

The strap on RX_CTRl is used for enabling or disabling auto-negotiation. If auto-negotiation is enabled then ANEG_SEL strap on LED_1 is used to select which speeds will be advertised during auto-negotiation. If ANEG_SEL is 0 then all speeds, 10M/100M/100M, will be advertised. If ANEG_SEL is 1 then only 100M and 1000M will be advertised during auto-negotiations.

Hi Aniruddha-san,

I believe ANEG_SEL is no effect whether 0 or 1 when disabling auto-negotiation (RX_CTRL=MODE4).
Is my understanding correct?

Best Regards,
Yaita

Hello Yaita-san,

Yes, if auto-negotiation is disabled then ANEG_SEL will not have a effect.
