TMS320F28069: Dumb HRPWM Question - Is 'B' channel required?

Part Number: TMS320F28069

Hello,

I was wondering - is it a hard requirement for the HRPWM module to use the 'B' channel?

I can configure the 'A' channel only, correct, and not suffer any consequences for not using the 'B' channel, correct?

Or, is it 'more correct' to configure using both channels - but then disabling the 'B' channel if it isn't used/required?

I realize the only ways to get the 'B' channel to have HRPWM resolution is to either enable channel path swapping or enable A signal output inversion on B.

Thanks,
John W.
