How to Use
When pin 7 is set to default Sync-Off function, pin 7 has bi-directional I/O func-
tion, which can receive pulse signal input from the external instrument and also
can output pulse signal to external instrument. The parameter requirements of
this pulse signal are as follows:
Level rise slope
Level fall slope
Minimum time width
for low level keep
The bi-direction I/O functions are introduced as below:

Not-Invert: No
Sync- This default function means that pin 7
Off performs bi-directional and synchronous
control over the turn-off of [On/Off]
under parallel connection.
Input Pin 7 receives the level signal from the
outside.
Output Pin 7 sends the digital signal (1, 0,
PWM) to the outside.

Basic Operation
By default (Not-Invert), the out-
put digital signal is 1 (i.e. low
level), and in the case of
Invert, the output is high level.
By default (Not-Invert), the out-
put digital signal is 0 (i.e. high
level), and in the case of
Invert, the output is low level.
