For memory represenation each component is allocated 16 bits each. Thus each pixel occupies a DWORD. Y210: Valid data occupies MSB 10 bits. LSB 6 bits are filled with zeroes. Y212: Valid data occupies MSB 12 bits. LSB 4 bits are filled with zeroes. Y216: Valid data occupies 16 bits, doesn't require any padding bits. First 16 bits stores the Y value and the next 16 bits stores one of the chroma samples alternatively. The first luma sample will be accompanied by first U sample and second luma sample is accompanied by the first V sample.
