(1) This is the secondary terminal at which the signal is also available. See Section 4.2.2.2 for more detail on how to select between the available terminals for input functionality.
(2) By default, the EMIF interface pins are the primary pins before configurating the IOMM (IO Muxing Module). The output buffers of these pins are forced to tri-state until enabled by setting
PINMMR174[8] = 0 and PINMMR174[9] = 1.”
