OMAP5912

Universal Serial Bus (USB)
This mode of operation implements only one I
internally combines ALTSCL and SCL, and ALTSDA and SDA. This means
that it is not possible to implement I
both links.
OMAP5912 supports a mode in which the OMAP5912 UART1.TX and
UART1.RX signals are brought out via USB pin group 0 pins. In this mode of
operation, top-level pin multiplexing is configured to provide the RX input on
USB.DP/UART1.RX and provide the TX output on USB.DM/UART1.TX. This
is configured using the USB_TRANSCEIVER_CTRL.CONF_USB0 register
(see
Figure
91).
USB_TRANSCEIVER_CTRL.CONF_USB0_ISOLATE to 1 to ensure that the
UART1 signals have no effect on the OMAP5912 USB controllers.
