ADC syncronous conversion - Hardware Triggers

[kyf]

Hello NXP team !

Can someone explain me how this setup is like ??

Please also, can someone explain me how does the ADC0_EOC works ?

A. Is this trigger enabled in after every end of ADC0 channel conversion ?

B. When does the eDMA 0/1/16/17 trigger goes high in order to trigger the ADC12 NormalConv or SyncStartPulse ?

C. I want with 1 trigger to start a chain of conversion in ADC0 and ADC1. Which signal should I use to do this !? (the TRGMUX_IP_OUTPUT_ADC12_0_EXTRG_SYNC_START_PULSE or TRGMUX_IP_OUTPUT_ADC12_0_EXTRG_NORMAL_CONV ???

D. If I use a DMA channel to be triggered from BCTU or FIFO1. Can I use the same DMA to start a parallel Normal Conversion for ADC0 and ADC1 ?!

Kind regards,

kyf
