Hello,

   

i am using CY8C4247AZI and i want to alternatively start and stop line and line_n.

   

In my project invert signal is require for that i am using both line and line_n. but i don't know 

   

how to stop line_n while line is running or generating PWM .

   

in next step i have to close line but line_n must be turn on and generate invert PWM..

   

 

   

 

   

Best Regard

Use a mux and a control register. Even an XOR should work

thanks bob ..

   

i tried with DE-multiplexer but i am not able to configure it properly  . i getting problem with demux width connection(selector pin) , which is taking value from digital input pin and for more output it need bus connection i don't know how to provide bus connection . so i use 1x2 demux it need only one select line and changing demux output pin properly . but i want to control demux output in run time not by physical gpio pin . then i use digital  constant to change demux selector value but it won't solve my problem .

   

please help......

Welcome in the forum,

   

but

   

Not a good idea to hijack a thread with quite a different topic for your use. Better create a new thread to get better help.
