6 channel PWM with 2 - 5 kHz frequency
Judging from your mentioning 62.5&nbsp;kHz as the base frequency for
pins 5&nbsp;and&nbsp;6, I assume you are talking about an Arduino Uno or
something similar.

If you set the timer&nbsp;0 to phase correct PWM mode (which is how the
Arduino core configures the other timers), then its base frequency is
about&nbsp;31.373&nbsp;kHz (F_CPU/510). With the prescaler set
to&nbsp;8, you get a PWM frequency of about&nbsp;3.922&nbsp;kHz on pins
5&nbsp;and&nbsp;6.

Note that you can set all three timers in this mode and have 6&nbsp;PWM
channels at this frequency. But note also that by reconfiguring
Timer&nbsp;0 you loose all the standard Arduino timing functions.
