This peripheral has dedicated control bits that flip input/output signals before handing them off to the OS. This is useful on my hardware because the UART is connected to an RS-422 transceiver with the +/- pins hooked up backward. Instead of a hack flipping all the bits before sending them, the hardware can do it for free. -- CONFIDENTIALITY NOTICE: This email and any attachments are for the sole use of the intended recipient and may contain material that is proprietary, confidential, privileged or otherwise legally protected or restricted under applicable government laws.
