DP83TC814S-Q1: DP83TC814S-Q1

Hi Hanamantappa,

Bit[12] has no effect if bit[13] is not asserted. Bit[13] must first be set to 1 to enable force polarity control, then bit[12] selects normal or inverted forced polarity.

Thanks,

Hello David,

Thanks for the answer.. can you please explain what is the normal polarity and forced polarity. What is difference between these two?

Hi Hanamantappa,

Auto-polarity is decribed in the DP83TC814 datasheet, the section is titled 8.4.5.2 Auto-Polarity Detection and Correction.

Normal polarity is the standard setting. Inverted polarity is when the TRD_M (negative) and TRD_P (positive) signals are flipped.

Forced polarity if when you  force it to one of these settings, otherwise the DP83TC814 will implement auto polarity correction.  

Best regards,

Melissa
