/**

* @file
|
|
* @brief Initialize system clock driver
|
|
*
|
|
* Initializing the timer driver is done in this module to reduce code
|
|
* duplication. Although both nanokernel and microkernel systems initialize
|
|
* the timer driver at the same point, the two systems differ in when the system
|
|
* can begin to process system clock ticks. A nanokernel system can process
|
|
* system clock ticks once the driver has initialized. However, in a
|
|
* microkernel system all system clock ticks are deferred (and stored on the
|
|
* kernel server command stack) until the kernel server fiber starts and begins
|
|
* processing any queued ticks.
