* Description : This function is called to initialize rt-thread's tick source (typically a timer generating

* interrupts every 1 to 100 mS).
|

*
|
||||
* We decided to use Timer #B0 as the tick interrupt source.
|

*
|

* Arguments : none
|

*
|
||||
* Returns :
|
||||
*
|
||||
* Notes : (1) Timer B channel 0 is setup as a periodic timer, generating an interrupt
|
||||
* OS_TICKS_PER_SEC times per second. The timer counts down and generates an interrupt
|
||||
* when it underflows.
|
||||
*
|
||||
* (2) The timer ISR handler, rt_hw_timer_handler(), is placed into the vector table in vectors.s34.
