## osInitialize

Syntax

#include <ultra64.h>
void osInitialize(void);
Explanation
It initializes various hardware components and software data structures internal to the N64. Specifically, this routine does the following:

- Enables the floating point control/status register to flush all denormalized numbers to zero and to cause an invalid operation exception when Not a Numbers (NaNs) are generated.
- Installs exception vectors.
- Initializes a TLB entry 31 for the debug port.

This routine should be called upon application startup prior to any interrupt or exception handling.
