What is "HSPI_CLK"?

"HSPI_CLK" is a signal on some microcontrollers that is used as the clock signal in High-Speed Serial Peripheral Interface (HSPI) communication.

HSPI is a variant of the Serial Peripheral Interface (SPI) communication protocol that is designed to support higher speeds, typically up to several megabits per second. HSPI is used in many applications, including wireless communication, video displays, and high-speed data acquisition.

In an HSPI setup, the clock signal is typically generated by the master device and sent to the slave devices on a dedicated clock line. The HSPI_CLK signal is the clock output from the master device and is used to synchronize the communication with the slave devices.

The specific characteristics of the HSPI_CLK signal, such as its voltage level, timing, and frequency, can vary depending on the specific microcontroller being used and the configuration of the HSPI interface. It is important to consult the datasheet and documentation for the specific microcontroller being used to understand the characteristics of the HSPI_CLK signal and how it should be used in a particular application.
