This library allows Arduino/Genuino Mega boards to control up to 9 servos with the integrated 16-bit hardware PWM timer/counter.

detach() vs detachall()

If no pin number is required for detach() (per docs), how do you reference which servo to detach? And then, what is the difference between:

detach() — Clears the used registers and stops the output of the attached pin. (no pin number!)
detachAll() — Clears the used registers and stops the output of ALL attached pins. (no pin number!)

Use all 3 timer outputs for a timer

Wanted to use your library but noticed you are using the wrong WGM mode.

Using WGM mode 14 (FastPWM with IRCn as TOP) you can use all 3 timer outputs and no need to define the TOP value by sacraficing the ORCnA.

This works:

TCCR3A = (2 << COM3A0) | (2 << COM3B0) | (2 << COM3C0) | (1 << WGM31) | (0 << WGM30);
TCCR3B = (1 << WGM33) | (0 << WGM32) | (2 << CS30);
TCCR3C = 0;

ICR3 = 20000;

OCR3A = 1000;
OCR3B = 1500;
OCR3C = 2000;

DDRE |= (1 << PE3) | (1 << PE4) | (1 << PE5);
