From the datasheet I have: Software Input On Field. Force the selected mux mode Input path no matter of MUX_MODE functionality. 1: Force input path of pad A14. 0: Input Path is determined by functionality of the selected mux mode (regular). So i think that in case of some peripheral this is not relevant but I need confirmation Michael > Best regards, > Benoît -- | Michael Nazzareno Trimarchi Amarula Solutions BV | | COO - Founder Cruquiuskade 47 | | +31(0)851119172 Amsterdam 1018 AM NL | | [`as] http://www.amarulasolutions.com | _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
