PRODUCTION DATA
During the link training process, the DP83TC812-Q1 100BASE-T1 Slave device is able to detect polarity reversal and automatically corrects the error. If polarity reversal is detected, the 100BASE-T1 Slave will invert its own transmitted signals to account for the error and ensure compatibility with the 100BASE-T1 Master. Polarity at the 100BASE-T1 Master is always observed as correct because polarity detection and correction is handled entirely by the 100BASE-T1 Slave.
Auto-polarity correction may be disabled in cases where it is not required. Disabling of auto-polarity correction is achieved via register 0x0553.
