59. When OE = V
60. Two dummy writes are issued to accomplish bus turnaround. The third instruction is the first valid write.
61. Chip enable or all byte enables are held inactive during the two dummy writes to avoid data corruption.
62. OE is deasserted and t
63. Any write scheduled to complete after OE is deasserted is pre-empted.
