Data inputs = D2, D3, D5, D6, D8 to D25 when C0 = 0 and C1 = 0.
Data inputs = D2, D3, D5, D6, D8 to D14 when C0 = 0 and C1 = 1.
Data inputs = D1 to D6, D8 to D10, D12, D13 when C0 = 1 and C1 = 1.
PAR_IN arrives one clock cycle (C0 = 0), or two clock cycles (C0 = 1), after the data to which it applies.
This condition assumes QERR is HIGH at the crossing of CK going HIGH and CK going LOW. If QERR is LOW, it stays latched LOW for
two clock cycles or until RESET is driven LOW.
