The section on RX Active says:
"9.2.2.3 RX Active The RXACTIVE bit is used to enable and disable the input buffer. This control can be used to help with power leakage or device isolation through the I/O. The characteristic of the signal is ultimately dictated by the mux mode the pad is put into.” Regards, John > > Jon > > -- > For more options, visit http://beagleboard.org/discuss > <http://beagleboard.org/discuss> > --- > You received this message because you are subscribed to the Google Groups > "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to beagleboard+unsubscr...@googlegroups.com > <mailto:beagleboard+unsubscr...@googlegroups.com>. > To view this discussion on the web visit > https://groups.google.com/d/msgid/beagleboard/96bee223-50d9-4913-9194-f4b6a3648e05%40googlegroups.com > > <https://groups.google.com/d/msgid/beagleboard/96bee223-50d9-4913-9194-f4b6a3648e05%40googlegroups.com?utm_medium=email&utm_source=footer>. > For more options, visit https://groups.google.com/d/optout > <https://groups.google.com/d/optout>. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
