            Description

            If SPM is used in interrupt mode, the netX SPI read/write functions are also called in the cifX Toolkit ISR function. Calling the cifX Toolkit ISR function in interrupt context and executing a OS_SpinLock() (wait mutex) can lead into a deadlock, if the mutex is used at the same time in task mode.
