SPI0_CLK | O | SPI0 Clock: SPI clock signal for the common flash/TPM interface. Supports 20 MHz, 33 MHz and 50 MHz. |
SPI0_CS0# | O | SPI0 Chip Select 0: Used to select the primary SPI0 Flash device. This signal cannot be used for any other type of device than SPI Flash. |
SPI0_CS1# | O | SPI0 Chip Select 1: Used to select an optional secondary SPI0 Flash device. This signal cannot be used for any other type of device than SPI Flash. |
SPI0_CS2# | O | SPI0 Chip Select 2: Used to select the TPM device if it is connected to the SPI0 interface. It cannot be used for any other type of device. |
SPI0_MOSI | I/O | SPI0 Master OUT Slave IN: Defaults as a data output pin for PCH in Dual Output Fast Read mode. Can be configured with a Soft Strap as a bidirectional signal (SPI0_IO0) to support the Dual I/O Fast Read, Quad I/O Fast Read and Quad Output Fast Read modes. |
SPI0_MISO | I/O | SPI0 Master IN Slave OUT: Defaults as a data input pin for PCH in Dual Output Fast Read mode. Can be configured with a Soft Strap as a bidirectional signal (SPI0_IO1) to support the Dual I/O Fast Read, Quad I/O Fast Read and Quad Output Fast Read modes. |
SPI0_IO2 | I/O | SPI0 Data I/O: A bidirectional signal used to support Dual I/O Fast Read, Quad I/O Fast Read and Quad Output Fast Read modes. This signal is not used in Dual Output Fast Read mode. |
SPI0_IO3 | I/O | SPI0 Data I/O: A bidirectional signal used to support Dual I/O Fast Read, Quad I/O Fast Read and Quad Output Fast Read modes. This signal is not used in Dual Output Fast Read mode. |
