SDADC in MPC5777C

[dineshmoka]

hi i am using SDADC in MPC5777c. when i am using single channel i am getting the result in SDADC_CDR register.i want to use multiplexed channels and want to store the result in some array.how to access the converted result which is stored in FIFO structure?

First of all I would note that SDADC module is not too suitable if you need to convert to perform fast switching between channels because of t_settling time between every switch. On the device there is also eQADC module present that is much better for this purpose. SDADC is well equipped for frequency-domain digital AC signal processing type applications where continuous conversion of one channel is needed(knock, cylinder pressure).

You may switch channels but need to count with the latency.
