• Control
Strobe signals are used for Command mode control. Data is retrieved when the strobe signal
is at low level. Strobe signals should maintain a stable low level state for at least 350 ms.
Before the next command, the strobe signal should maintain a stable high level state for at
least 650ms and then set it to a low level.
