* (IOMUXC_SW_MUX_CTL_PAD_x). * - Each pad can have but not necessarily does have an input routing register * (IOMUXC_x_SELECT_INPUT) * * The three register sets do not have a fixed offset to each other, * hence we order this table by pad control registers (which all pads * have) and put the optional i/o routing registers into additional * fields. * * The naming convention for the pad modes is
