External trigger for regular channels for ADC1 and ADC2
Source Type EXTSEL[2:0]
TIM1_CC1 event
000
TIM1_CC2 event 001
TIM1_CC3 event Internal signal from on-chip 010
TIM2_CC2 event timers
011
TIM3_TRGO event 100
TIM4_CC4 event 101
EXTI line11/TIM8_TRGO
event (1)(2)
External pin/Internal signal from
on-chip timers
1. The TIM8_TRGO event exists only in High-density devices.
2. The selection of the external trigger EXTI line11 or TIM8_TRGO event for regular channels is done through
configuration bits ADC1_ETRGREG_REMAP and ADC2_ETRGREG_REMAP for ADC1 and ADC2,
respectively.
