DP83867IS: STRAP_STS1 and STRAP_STS2

K.Yaita

Part Number: DP83867IS

Hi Team,

There are some bits in the STRAP_STS1 and STRAP_STS2 Register without corresponding Strap pins.
Are the following red-parts "Strap" typo?

Hi Yaita,

They are not typos.
Please see section 8.5.1 in the datasheet.

Kind regards,
Ross

Hi Ross-san,

Thank you for your reply.
I saw section "9.5.1 Strap Configuration" however couldn't understand..

For example, regarding STRAP_LINK_DOWNSHIFT_EN, how to enable by strap configuration?

Best Regards,
Yaita

Hi Yaita,

I apologize. You are correct. There appears to be some typos in the register map listing. I will inform my colleagues about this. Thank you for the catch.

Kind regards,
Ross

Hi Yaita-san,

The strappable options on the DP83867IS are:
PHY_ADD[3:0] = STRAP_PHY_ADD
Autonegotiation = STRAP_ANEG_DIS
RGMII RX Clock Skew = STRAP_RGMII_CLK_SKEW_RX
RGMII TX Clock Skew = STRAP_RGMII_CLK_SKEW_TX
Mirror mode = STRAP_MIRROR_EN
SGMII enable = STRAP_SGMII_EN
SPEED_SEL = STRAP_SPEED_SEL

All other bit fields in register 0x006e and 0x006f are not dependent on strap and default to 0, RO
