[MPC5748G] Can not find the ADC external trigger source

Hello,

I'm working on ADC module in MPC5748G and want to use an external trigger to start ADC injected conversion.

I'm using  MPC5748GRM Rev. 6, 10/2017, at https://www.nxp.com/docs/en/reference-manual/MPC5748GRM.pdf 

And It describes at  32.6.1.3.1 Starting injected conversion

To start an injected conversion via external trigger, enable external triggering by setting MCR[JTRGEN]=1. A programmed event (rising/falling edge depending on MCR[JEDGE] bit) on the injection trigger input starts the injected conversion

 

 

But I can't find the external trigger source to generate trigger source.

Please help to figure out the external trigger source for ADC injected conversion.

 

P/S: The RM also describes BCTU trigger mode but as I understand It will not start an injected conversion.

 

Many Thanks,

Anh
