Default settings for PINMUX0 and PINMUX1 registers are underlined. B. EMIFA Block: This figure only shows the Major Config Options in the EMIFA Block based on the AEM and RMII settings. Actual pin functions in the EMIFA Block are further determined by other PINMUX fields. C. McBSP0 pins span multiple blocks (Serial Port Sub-Block0 and Timer0 Block). Serial Port Sub-Block0 contains most of the pins needed for McBSP0 operation. Timer0 Block contains the optional external clock source input CLKS0. Figure 3-10.
