I'm using 5744P, how can I use multiple ADC channel with SW trigger?
I found there're something about PDB and DMA, but I can't understand.
Could anyone tell me about these function and setting?
PDB is not available on MPC5744P, the CTU is used here to trigger and send commands for ADC.
However you can simply do chain conversion directly in the ADC module. Simply select desired channels to be converted in the NCMR and then set MCR[NSTART] bit. If one shot mode is selected MCR[MODE]=0 the MSR[NSTART] will be cleared after conversion chain is finished (all selected channels are converted) and ISR[ECH] flag is set too.
Thanks for reply. I also want to know is there PDB or CTU on 5746R? Please tell me.
the MPC5746R contains BCTU module, refer to device RM.
