* Parameters:
*
* @param uint32 period
* Period of the timer in u-seconds.
* @param uint8* cnt
* The value written to T2CT (counter). This value is returned to enable
* a fast setup (without calculation) using the SET_TIMER2_COUNTER.
* @param uint8* presc
* The value written to T2PR (prescaler). This value is returned to enable
* a fast setup (without calculation) using the SET_TIMER2_PRESCALER.
*
* @return bool
Returns FALSE if period is too large, TRUE otherwise.

* @fn halSetTimer34Period
*
* @brief
* This function sets the period of timer 3 or 4 according to the value of
* _timer_. The two timers are identical. Clock division is used to fit the
* desired period within the timer range. If the period is too short or too
* long the function returns 0. If the period is successfully set, the
* function returns the byte value written to the timer register. This
* value can be used to set the pulse length if the timer is used for PWM.
* If _period_ is set to 0, maximum timeout value will be used.
*
* Parameters:
*
* @param byte timer
* Indicates which timer to configure. Must be either 3 or 4
* (0x03 or 0x04).
* @param dword period - Describe value.
* The desired period in microseconds.
*
* @return byte
* The value written to the TxCC0 register. The timer is incremented up
* to this value before the timer is reset. This value may be used to
* set the pulse length in PWM mode.
