What is the maximum number of PWM channels for nRF51-DK with SoftDevice running?

Question

Since the SoftDevice uses Timer0, am I correct in assuming that the maximum number of PWM channels for nRF51-DK with SoftDevice running is 4? (Two each on Timer1 and Timer2.) 
 Thanks

Hi, 
 You can have a maximum of 4 PWM channels, this is because we have 4 GPIOTE channels. 
 Nick is correct that in theory we could have 8 due to the timers having 4 compare events, however you typically will need one of those compare events to do a reset, so we end up with a theoretical max of 6. 
 Best regards,
