16.5.3 User Channel MUX

Each event user can be connected to one channel and several users can be connected to the same channel. The following table lists all Event System users with their corresponding user ID number and name. The user name is given by combining USER with Peripheral and Input from the table below in the following way: USERPERIPHERALINPUT.


USER			Async/Sync	Description

`0`	CCL	LUT0A	Async	CCL LUT0 event input A
`1`		LUT0B		CCL LUT0 event input B
`2`		LUT1A		CCL LUT1 event input A
`3`		LUT1B		CCL LUT1 event input B
`4`		LUT2A		CCL LUT2 event input A
`5`		LUT2B		CCL LUT2 event input B
`6`		LUT3A⁽¹⁾		CCL LUT3 event input A
`7`		LUT3B⁽¹⁾		CCL LUT3 event input B
`8`	ADC0	START	Async	ADC start on event
`9`	EVSYS	EVOUTA	-	EVSYS pin output A
`10`		EVOUTC		EVSYS pin output C
`11`		EVOUTD		EVSYS pin output D
`12`		EVOUTF⁽¹⁾		EVSYS pin output F
`13`	USART0	IRDA	Sync	USART0 IrDA event input
`14`	TCE0	CNTA	Sync	Count on positive event edge
				Count on any event edge
				Count while event signal is high

`17`		COUNT	Sync	Count on event
`18`	TCB1	CAPT	Sync	Timeout check
				Input capture on event
				Input capture frequency measurement
				Input capture pulse-width Measurement
				Input capture frequency and pulse width measurement
			Both	Single shot
`19`		COUNT	Sync	Count on event
`20`	TCF0	COUNT	Async	Event as clock source
`21`	TCF0	ACTION	Async	Event action
`22`	WEX0	FAULTA	Async	Fault input A
`23`		FAULTB	Async	Fault input B
`24`		FAULTC	Async	Fault input C

Note:

Not all peripheral instances are available for all pin counts. Refer to the Peripherals and Architecture section for details.
