Signal Name
Description
STROBE is a strobe pulse used to read data from the host

computer. The pulse width must be more than 0.5
Normally it is HIGH, and data is latched at the
edge of
this signal.
DATA 1 to 8 are parallel data bits. When the signal is HIGH,
the data bit is 1, and when it is LOW, the data bit is O.
