3 x 64-bit data bus, standard transmission (BS1 = H, BS2 = L)
The data bus is in 3-bit mode (DB1 to DB3 active) for BS1 = H and BS2 = L.
Data on DB1 is sampled by the first clock pulse and shifted from position 1 to position 190
after 64 clock pulses. The data is then applied to output 190, on the high-to-low transition of
/STB.
3 x 64-bit data bus transmission
6 x 32-bit data bus, standard transmission (BS1 = L, BS2 = L)
The data bus is in 6-bit mode (DB1 to DB6 active) for BS1 = L and BS2 = L.
