Figure 41-6. Event Input Selection

I/O Pin Inputs (IO)

When the IO pin is selected as LUT input (LUTCTRLx.INSELy=IO), the corresponding LUT input will be

connected to the pin, as shown in the figure below.

Figure 41-7. I/O Pin Input Selection

Analog Comparator Inputs (AC)

The AC outputs can be used as input source for the LUT (LUTCTRLx.INSELy=AC).

The analog comparator outputs are distributed following the formula:

IN[N][i]=AC[N % ComparatorOutput_Number]

With N representing the LUT number and i=[0,1,2] representing the LUT input index.

Before selecting the comparator output, the AC must be configured first.

The output of comparator 0 is available on even LUTs ("LUT(2x)": LUT0, LUT2) and the comparator 1

output is available on odd LUTs ("LUT(2x+1)": LUT1, LUT3), as shown in the figure below.
