DM648 GPIO0-7 pins and/or Pin Mux Register Select

The Documentation is confusing to me so I've got to ask.  I want to use the User Defined LEDs on my EVM board which are tied to GPIO2-GPIO5, but I'm not having any luck.  I believe I am setting up the GPIO module correctly, however, I'm not sure about the PinMux Select Register.  The instructions are unclear to me as to if the GPIO0-7 lines are even muxed or not (as shown in Table 3-8 in the tms320dm647 datasheet).

Also, what does Table 3-7 mean with the Unmuxed or Muxed Columns?  Is this the same as Primary and Secondary Functions of the Pins?

For instance, the SPI_UART_EN field PINMUX[13:12] controls if SPICLK is enabled, disabled or in a 3-state.  It also controls if the SPI is muxed, UART is muxed, or a combination of both is muxed out.

Thanks much! This makes it much easier to read and understand for me, as well as me being able to better decode the programming table on the pin mux.
