+// -----------------------
+// 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
