nrf52832 with freertos，PPI SAADC multi channel

[Coder_hope]

hello everyone：

       I have an issue on nrf52832 running freertos based on SDk 15.0,I am using PPI and SAADC to get 2 channels  data .I find that if I  change the configuration and use internal LFRC,the 2 channels data is mixed ,for example: the chennel 0`s data is replaced with channel1,channel 1`s data is replaced with channel 0 too,but the advertising is fine and the ble master receives ok; if I change the configuration and use external LFRC,the 2 channels data are correct,he advertising is fine and the ble master receives ok.

      so,is there any configuration wrong in my project?or I have to use external LFRC?
