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.

Note:

The TCC selection for each LUT follows the formula:

IN   =   % C_Instance_Number

Where N represents the LUT number.

Before selecting the waveform outputs, the TCC must be configured first.

Serial Communication Output Transmit Inputs (SERCOM)

The serial engine transmitter output from Serial Communication Interface (SERCOM TX, TXd for USART,

MOSI for SPI) can be used as input source for the LUT. The figure below shows an example for LUT0

and LUT1. The SERCOM selection for each LUT follows the formula:

IN   = [ % SERCOM_Instance_Number

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

Before selecting the SERCOM as input source, the SERCOM must be configured first: the SERCOM TX

signal must be output on SERCOMn/pad[0], which serves as input pad to the CCL.
