STM32 MCUs Embedded software

Question about the aPDMBuffer array in the STM32 smartmic firmware. In what format are the samples of the two Digital MEMS channels stored in the aPDMBuffer array? Are the samples arranged in an alternative fashion in the aPDMBuffer array?

 Does aPDMBuffer[0] refer to mic1 sample and aPDMBuffer[1] refer to mic 2 sample?
