Example Usage
The code below indicates how to write BSP_OS_TickISR() if all interrupts vector to a common location, and the interrupt handler simply calls BSP_OS_TickISR(). As indicated, this code can be written completely in C and can be placed in bsp_os.c of the board support package (BSP) and be reused by applications using the same BSP.
The pseudo code below shows how to write BSP_OS_TickISR() if each interrupt directly vectors to its own interrupt handler. The code, in this case, would be written in assembly language and placed either in bsp_os_a.asm of the board support package.
