1.1.9 Serial Communication Output Transmit Inputs (SERCOM)

The SERCOM transmitter output can be used as input source. The transmitter output is TxD for USART, MOSI for SPI, and SDA for I2C. SERCOM input is selected by writing the Input y Source Selection bit group in the LUT Control x register (LUTCTRLx.INSELy) to 0x9. LUTx can be connected to SERCOMx, as indicated in the following table. Before selecting the SERCOM as input source, the SERCOM must be configured.

Table 1-5. LUT SERCOM Inputs
LUT	IN[x]	SERCOM
LUT0	x = 0,1,2	SERCOM0
LUT1	x = 0,1,2	SERCOM1
LUT2	x = 0,1,2	SERCOM2
LUT3	x = 0,1,2	SERCOM3
