+ * USE_OCR2A_AS_TOP [undefined by default]
+ * Boards that use TIMER2 for PWM have limitations resulting in only a few possible frequencies on TIMER2:

+ * A greater range can be achieved by enabling USE_OCR2A_AS_TOP. But note that this option blocks the use of
+ * PWM on pin OC2A. Only use this option if you don't need PWM on 0C2A. (Check your schematic.)
+ * USE_OCR2A_AS_TOP sacrifices duty cycle control resolution to achieve this broader range of frequencies.
