SPI Slave NSS Interrupt - ST Community

WebIn master mode, NSS can be used either as output or input. As an input it can prevent multimaster bus collision, and as an output it can drive a slave select signal of a single slave.

WebThe Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems.The interface was developed by Motorola in the mid-1980s and has become a de facto standard.Typical applications include Secure Digital cards and liquid crystal displays.. SPI … Webpulses on NSS output signal between data frames for a duration of one SPI clock period when there is a continuous transfer of data. The data is then interleaved by two SPI clock periods. The clock phas e is fixed in this mode. Another enhanced mode is the TI mode where the data flow is synchronized by the NSS pulses, provided by the master,
