CORESwitchBeepStatus
Indicates if a switch beep is generated for all switch depression.
HWSTPDataBuffer
On all switch depressions, the kernel will grab a copy of the
100hz free running counter data and store it in this variable.
This can then be used by the foreground state handler to be pass
as parameters to activate or deactivate any kernel timer resources.
4.10 Common Variables
When an application uses a variable that will be used only for the duration of the execution of the state
handler, it is best to store them in common variables. The advantages are two-fold. First, it reserves the
heap memory for important variables allowing for more applications to be active at any given time.
Second, the common variables are located in fixed memory, so direct addressing which uses less ROM can
be used instead of the index relative addressing mode required for ASD.
The kernel allocates two types of common variables. The foreground and background common variables.
