The Control Module (Section 9), specifically 9.3.1 "Control Module Registers" and 9.3.1.50 "conf_<module>_<pin> Register" document the pin mux registers. > Does this sound right: > > L16 set for UART3_TX 0x0138 0x81 /* uart3_txd mode 1 */ > L17 set for UART3_RX 0x0134 0x81 /* uart3_rxd mode 1 */ If you want to know what data to put into the pin mux registers, you need to refer to Section 2.2 and Table 2.7 of the data sheet, "Ball Characteristics". This lists the physical pin characteristics and the various legal mode settings. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
