RTOS API

This library function invokes a RTOS software interrupt. Refer to this RTOS API function's documentation for more details.

On SC1x3/SC2x (RTOS version >=1.13, CLIB version >=2.10) there's also a version of this function which uses dynamic linking instead of a software interrupt, which reduces the function's overhead and thus speeds up your application. This function's name is spi_init_dyn. You should however not use this function directly. Instead you should add the define SPI_DYN_LINK to your program before including the CLIB's header file(s):
#define SPI_DYN_LINK
#include <clib.h>
This will map the original function's name to the dynamic linking version. This way you can also easily switch existing programs to dynamic linking.
