Short answer is all servos will work at the same time.
Servo requires 1ms-2ms pulse every 20ms.
Because of that, we only need one CCR to control all servos at the same time. We shift start time of the pulse for each servo, so they are still repeated every 20ms, but occur one after another, never at the same time.
We set CCR for the first servo and turn it on, then when done, we turn it off, set CCR for servo 2 and turn it on. We repeat that 6 times and then we calculate time needed to complete 20ms and set CCR.
