What is the Intel(R) Serial IO SPI Host Controller - 43AB Driver?
The Intel(R) Serial IO SPI Host Controller - 43ABSerial Peripheral Interface (SPI) bus. SPI is a high-speed interface used to connect various low-level peripherals like sensors, EEPROMs, and microcontrollers to the main processor or chipset.
This SPI Host Controller driver facilitates the interaction between Windows and devices using the SPI protocol, ensuring proper operation of those connected peripherals. The driver is typically used on systems with Intel chipsets and is part of Intel's Serial I/O (Input/Output) technology, which includes various interfaces such as I2C, SPI, UART, and others.
In particular, the "43AB" identifier is a specific hardware version of the controller, and the driver helps Windows recognize and work with that version correctly.
