ADC DMA data size mismatch

A 12-bit ADC result is moved by DMA into a uint16_t buffer. The DMA peripheral size is set to half-word but memory size to word. What happens?

A.Nothing happens; the DMA ignores the size settings for the ADCB.The DMA stops with an alignment error on every single transferC.Only the high byte of each sample is kept in the bufferD.Each sample is written as 32 bits, so zeros appear between samples
