CC3220SF SPI回调函数

SPI非阻塞模式下的发送完成的回调函数属于硬件中断还是软件中断？如果是软件中断，优先级是多少？

Kevin Qiu1：

In callback mode, a SPI transaction functions asynchronously, which means that it does not block code execution. After a SPI transaction has been completed, the SPI driver calls a user-provided hook function. Callback mode is supported in the execution context of tasks and hardware interrupt routines.
