RTOS I
The Narrowband Chipset driver requires the use of some Real-Time Operating System (RTOS)
resources. In this section of the manual, a listing of each required resource is shown, along with a
declaration and any specific porting instructions. It is the responsibility of the user to connect
these requirements into the RTOS, either by defining a macro or by writing a function for each
item listed. Care should be taken when matching parameters and return values.
