Hi Lanco_m4,
You are correct for the Kinetis SAR ADC module. Each module has two sample registers that can be configured to trigger simultaneously or delayed from one another using the PDB (Peripheral Delayed Block).
You can use a "static" method setup the ADC modules to sample different pins but this limits you to the two samples per ADC module.
If you use the other features of Kinetis like the eDMA and the various methods that allow the peripheral to trigger one another, then a "dynamic" method can be used:
ex: PIT timer used to trigger the eDMA to transfer ADC command to trigger the ADC sample. When the ADC sample completes, it can trigger the eDMA to get the result from ADC module and move to SRAM.
To summaries, if you have 2 or less samples per ADC module you want then a static approach may work. If you have more than 2 samples per ADC module then you need to use a dynamic approach (fast approach) that allows the hardware to reconfigure your ADC for samples or use dynamic code to setup ADC modules (slower approach).
Hope this helps.
Regards,
David
