b9 PDTA Parallel Data Allocation*
3
When data word length is 8 or 16 bits:
0: The lower bits of parallel data (SSIFTDR, SSIFRDR) are
transferred prior to the upper bits.
1: The upper bits of parallel data (SSIFTDR, SSIFRDR) are
transferred prior to the lower bits.
When data word length is 18, 20, 22, or 24 bits:
0: Parallel data (SSIFTDR, SSIFRDR) is left-justified.
1: Parallel data (SSIFTDR, SSIFRDR) is right-justified.
