	InitTimers() //Initializes all timers. Needs to be called before changing the timers frequency or setting the duty on a pin
	InitTimersSafe()	//Same as InitTimers() except timer 0 is not initialized in order to preserve time keeping functions
	pwmWrite(uint8_t pin, uint8_t val)	//Same as 'analogWrite()', but it only works with initialized timers. Continue to use analogWrite() on uninitialized timers
	SetPinFrequency(int8_t pin, int32_t frequency)	//Sets the pin's frequency (in Hz) and returns a bool for success

	Timer1_GetFrequency()	//Gets the timer's frequency in Hz
	Timer1_SetFrequency(int frequency)	//Sets the timer's frequency in Hz
	Timer1_GetPrescaler()	//Gets the value (not bits) of the prescaler. Don't know what this means? Don't worry about it, just use SetFrequency(int frequency)
	Timer1_SetPrescaler(enum value)   //	Sets the prescaler*
	Timer1_GetTop()	//Gets the timer register's maximum value
	Timer1_SetTop(int top)	//Sets the timer register's maximum value
	Timer1_Initialize()	//Initializes the timer
