5.3.2.2. RX Polarity Inversion Feature

The RX polarity inversion feature inverts each bit of the data received from the PMA. If the data received is a 10-bit data. Bit[0] content is inverted to its complement, ~bit[0], bit[1] is inverted to its complement, ~bit[1], bit[2] is inverted to its complement, ~bit[2], and so on. For example, if the 10-bit data is 1111100000, the polarity inversion feature inverts it to 0000011111.
