6 RTOS INTERFACE
The S/UNI-4x622 driver requires the use of some RTOS resources. In this section, 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 writing a function for each item listed. Care should be taken when matching
parameters and return values.
