#include <nitro/os.h>void OS_InitIrqTable( void );None.
None.
This function initializes the IRQ interrupt table.
The IRQ interrupt table is a table that is used to register which functions to jump to when an IRQ interrupt occurs. The table is divided along each IRQ interrupt cause.
Once this function has been called to initialize the table, functions that do nothing in response to most interrupts will have been set; however, DMA, NEW DMA, and TIMER interrupts register interrupt handlers that are prepared on the OS side. If the user registers a handler for these interrupts, these interrupts will be called from the interrupt handler provided by OS. The user does not need to be aware of this difference. Immediately after OS_InitIrqTable() is called, it should appear as though nothing is being done for any of the interrupts.
The user application does not need to call this function because it is called by the OS_Init function.
