DP83869HM: Impedance Control for MAC I/Os

Part Number: DP83869HM

Hi team,

Accodring to the datasheet below, default is set to 50 Ω by trim before shipping the device from TI, but the default register value of MAC_IMPEDANCE_CTRL can vary by process. Does this mean the register value of MAC_IMPEDANCE_CTRL is not 10h after resetting? Although the default value of MAC_IMPEDANCE_CTRL is 10h.

Regards,

Noriyuki Takahashi
