SCK, or Serial Clock, is a signal used in synchronous serial communication protocols to control the timing of data transmission between devices. It plays a crucial role in protocols like SPI (Serial Peripheral Interface), where it ensures that both the master and slave devices are synchronized during data transfers. The SCK signal defines when data is valid and should be read or written, making it essential for accurate communication between devices.
congrats on reading the definition of SCK. now let's actually learn it.
