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 #	User Name		Async/Sync	Description
USER #	Module	Input	Async/Sync	Description
0x00	CCL	LUT0A	Async	CCL LUT0 event input A
0x01		LUT0B		CCL LUT0 event input B
0x02		LUT1A		CCL LUT1 event input A
0x03		LUT1B		CCL LUT1 event input B
0x04		LUT2A		CCL LUT2 event input A
0x05		LUT2B		CCL LUT2 event input B
0x06		LUT3A		CCL LUT3 event input A
0x07		LUT3B		CCL LUT3 event input B
0x08	ADC0	START	Async	ADC start on event
0x09	EVSYS	EVOUTA⁽¹⁾	Async	EVSYS pin output A
0x0A		EVOUTC		EVSYS pin output C
0x0B		EVOUTD⁽¹⁾		EVSYS pin output D
0x0C		EVOUTF⁽¹⁾		EVSYS pin output F
0x0D	USART0	IRDA	Sync	USART0 IrDA event input
0x0E	USART1	IRDA	Sync	USART1 IrDA event input
0x0F	TCA0	CNTA	Sync	Count on event or control count direction
0x10	TCA0	CNTB	Sync	Restart on event or control count direction
0x11	TCB0	CAPT	Both⁽²⁾	Start, stop, capture, restart or clear counter
0x12	TCB0	COUNT	Sync	Count on event
0x13	TCB1	CAPT	Both⁽²⁾	Start, stop, capture, restart or clear counter
0x14	TCB1	COUNT	Sync	Count on event
0x15	TCB2⁽¹⁾	CAPT	Both⁽²⁾	Start, stop, capture, restart or clear counter
0x16	TCB2⁽¹⁾	COUNT	Sync	Count on event
0x17	TCD0	INPUTA	Async	Fault or capture
0x18	TCD0	INPUTB	Async	Fault or capture

Note:

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