Does anyone know the default contents of the PWMA register for the IsopodX? In the near future I will be changing the PWM Configure Register to allow for complimentary operation of the PWMA channels and would like the current contents before I change things. Thanks in advance.

PWM is default for INDEPENDENT on the current V0.82, and for future V1.0 as well.

I have version .6 and thus do not have the INDEPENDENT word. I was looking for the individual bits for this register.

Also - I would like to upgrade to a newer version. I paid for the license several months ago and recieved 0.62 or 0.64 Should this have been the version I received or should it have been a newer version? Thanks for responses - in advance

Hello again,
Does PWMA0 COMPLIMENTARY mean that when pin PWMA0 goes pulse width modulation at a particular duty cycle that pin PWMA1 goes to PWMA1 OFF state or is PWMA1 actually the inverse duty cylcle of PWMA0? Thanks in advance for your reply.

It simply inverses the duty cycle of its complimentary pair. One pulses high the other goes low, and vice versa...

Im still a little confused by your explanation - im sorry for asking the same thing again and again

If PWMA0 goes to 40/60 on/off duty cycle does PWMA1 go to 60/40 on/off as complimentary or does PWMA1 go OFF (zero volt)?

Low meaning 0V?
