Hi Anton,
With the Multo-channel configuration the sequence would be First through last channel. CH0, CH1 ... LAST_CH
Each channel will take the (1/ODR) time for that channel. i.e if two channels are configured CH0 and CH1 the first conversion result will be avilable after (1/ODR0) followed by (1/ODR1) and this repeats.
