USER

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

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 Async EVSYS pin output A
0x0A EVOUTB EVSYS pin output B
0x0B EVOUTC(1) EVSYS pin output C
0x0C USART0 IRDA Sync USART0 IrDA event input
0x0D USART1 IRDA USART1 IrDA event input
0x0E TCA0 CNTA Sync Count on event or control count direction
0x0F CNTB Restart on event or control count direction
0x11 TCB0 CAPT Both(2) Start, stop, capture, restart or clear counter
0x12 COUNT Sync Count on event
0x13 TCB1 CAPT Both(2) Start, stop, capture, restart or clear counter
0x14 COUNT Sync Count on event
Notes:
  1. 1.Not all peripheral instances are available for all pin counts. Refer to the Peripherals and Architecture section for details.
  2. 2.Depends on the timer operational mode.
