S32K312 bctu multiple parallel conversions

[Vandarkholme]

hello! refer to post "Example S32K312 PIT BTCU parallel ADC FIFO DMA DS3.5 RTD300 - NXP Community" I write my adc demo,  my question is:

can I set bctu list like this rule(channel of adc0 is more than adc1, there is 10 adc0 channels and 2 adc1 channels)?

1. adc0-p0
2. adc0-p1
3. adc0-p2
4. ..........
5. adc0-p9(last channel)
6. adc1-p0
7. adc1-p1(last channel)

or bctu mpc list must set like:

1. adc0-p0
2. adc1-p0
3. adc0-p1
4. adc1-p1(last channel)
5. adc0-p2
6. .........
7. adc0-p10(last channel)

thanks!

Hi,

if you set a trigger to do MPC (multiple parallel conversions), means you set more ADCSELx bits in TRGCFG then subsequent n items in your list specifies channels parallelly converted. So second option you outlined is correct
