ETRIGx are external trigger signals to the eQADC module. Still it represents internal signals which source can be selected by the SIU.ISEL[4-7] registers. See chapter 18.104.22.168 and Table 3-27 to Table 3-38 of the device Reference manual.
For example Table 3-27. eQADC_A Command FIFO 0 Trigger Sources
So many PIT, eTPU and eMIOS channels can be selected and also you can locate 2 external signals called “eTRIG0 pin” and “eTRIG1 pin”. These are available on pads AF23 and AD6(AA8)
