35.7 Polarity

Receive and transmit polarity is user selectable and affects all modes of operation.

The idle level is programmable with the TXPOL and RXPOL polarity control bits. Both control bits default to ‘0’, which selects a high idle level for transmit and receive. The low level Idle state is selected by setting the control bit to ‘1’. TXPOL controls the TX idle level. RXPOL controls the RX idle level.
