Hi guys,

Use WGM mode 14 which uses the ICR register to set the top.

If we start with a prescalar of 1, we want each cycle of our PWM
output to last 1600 clock cycles (@16 MHz), so you could set ICR to
1600, and vary OCR between 0 and 1600 to control the duty cycle.

Picking a prescalar of 8, and setting the ICR to 200 will give the same effect.
