// PWM FREQUENCY PRESCALER
// -----------------------
// Written by Kiwisincebirth 2014
// Revised by MacTester57 (aka TheDIYGuy999) to allow correct PWM frequencies (confirmed with oscilloscope). January 2015
// - prescale variable: replaced uint8_t with uint16_t data type (fixes bug, which did not allow frequencies < 492Hz)
// - mode variable: replaced hex format with binary to make it more readable, if compared with bit tables in the 32U4 manual
// - added comments
