OMAP L138 UART0

Inderjit,

The UART has dedicated single-ended transmit and receive pin functions so the module does not have native support for RS485.

_{Yes, I understand that.  I will be using an external half-duplex RS485 transciever.  The issue is enabling the transmitter, since the receive/tranmit lines are shared.  Some CPUs have the ability to auto-enable the external transceiver for transmit vs. having to do this via software control using a GPIO.  If this is not built-in to the UART, it will be a fair bit of software overhead (and we won't be able to use the transmit FIFO).}
