Timer/Counter Inputs (TC)
The TC waveform output WO[0] can be used as input source for the LUT (LUTCTRLx.INSELy=TC). Only
consecutive instances of the TC, i.e. TCx and the subsequent TC(x+1), are available as default and
alternative TC selections (e.g., TC0 and TC1 are sources for LUT0, TC1 and TC2 are sources for LUT1,
etc). See the figure below for an example for LUT0. More general, the Timer/Counter selection for each
LUT follows the formula:
IN � � = ��������� � % TC_Instance_Number
IN � � = ������������� � + 1 % TC_Instance_Number
Where N represents the LUT number and i represents the LUT input index (i=0,1,2).
Before selecting the waveform outputs, the TC must be configured first.

Timer/Counter for Control Application Inputs (TCC)
The TCC waveform outputs can be used as input source for the LUT. Only WO[2:0] outputs can be
selected and routed to the respective LUT input (i.e., IN0 is connected to WO0, IN1 to WO1, and IN2 to
WO2), as shown in the figure below.
Before selecting the waveform outputs, the TCC must be configured first.
