16.3.19 Injected channel management

Triggered injection mode

To use triggered injection, the JAUTO bit in the ADCx_CFGR register must be cleared.

1. Start the conversion of a group of regular channels either by an external trigger or by

setting the ADSTART bit in the ADCx_CR register.

2. If an external injected trigger occurs, or if the JADSTART bit in the ADCx_CR register is

set during the conversion of a regular group of channels, the current conversion is
