Hello,
I connected my TI DSP TMS320LF2810's PWM signals output pins to the pins in Bank3 of my CPLD chip EPM1270F256.
There are overall 6 PWM signals from DSP to CPLD chip. However, there are only two channels of PWM signals can be seen from DSP output pins to CPLD input pins. The other four channels have no signals at all!
I am pretty much sure that my DSP code is fine, which means that there are definitely 6 PWM outputs. And, I checked all 6 input pins in CPLD chip which are set the same as "Direction - input" and " 3.3V-LVTTL(default)" .
But, why are there only two channels of PWM signals can be output from DSP but the signals in the other four channels are all MISSING?
I do appreciate your help if you could shed some light here...

to make sure you have 6 active dsp outputs connect one known active pwm output to all 6 outputs and check.
