The following table describes the
function available on every pin for each device package.
Note: Each digital I/O on a device is mapped to a specific Pin Control Management
Register (PINCMx) that lets users configure the desired Pin
Function using the PINCM.PF control bits. The IOMUX only supports
connecting one IOMUX-managed digital function to the pin at the same time. The
PINCM.PF and PINCM.PC in IOMUX are recommended to be set to 0 when non-IOMUX
managed functions (such as analog connections) are intended to be used on a pin.
However, non-IOMUX managed signals (such as analog inputs and WAKE inputs) can
be enabled on a pin at the same time that an IOMUX managed digital function is
enabled on the pin, provided there is no contention between the functions. In
this case, the designer must verify that no contention exists between the
functions enabled on each pin.
