B1 and B2 = bypass serial data from outside source.
S1 – Sn + 1 = serial scan data from outside source.
S1 – Sn = RAMs input register contents.
Scan order is: A6, A4, A2, A0, D8, Q8, D6, Q6, D4, Q4, D2, Q2, D0, Q0, A18, A1, A3, A5, A7, A8, A9, A10, A11, A12, A13, Q1, D1, Q3, D3, Q5, D5, Q7, D7, A15, A16, A14, A17, E, G, W, K.
