GPP_A0 / ESPI_IO0 | I/O | eSPI Data Signal 0: Bi-directional pin used to transfer data between the PCH and eSPI slave device. |
GPP_A1 / ESPI_IO1 | I/O | eSPI Data Signal 1: Bi-directional pin used to transfer data between the PCH and eSPI slave device |
GPP_A2 / ESPI_IO2 / SUSWARN# / SUSPWRDNACK | I/O | eSPI Data Signal 2: Bi-directional pin used to transfer data between the PCH and eSPI slave device |
GPP_A3 / ESPI_IO3 / SUSACK# | I/O | eSPI Data Signal 3: Bi-directional pin used to transfer data between the PCH and eSPI slave device |
GPP_A4 / ESPI_CS0# | O | eSPI Chip Select 0: Driving CS# signal low to select eSPI slave for the transaction. |
GPP_A5 / ESPI_CLK | O | eSPI Clock: eSPI clock output from the PCH to slave device. |
GPP_A6 / ESPI_RESET# | O | eSPI Reset: Reset signal from the PCH to eSPI slave. |
GPP_A7 / ESPI_CS1# | O | eSPI Chip Select 1 :Driving CS# signal low to select eSPI slave for the transaction. |
GPP_A10 / ESPI_ALERT0# | I | eSPI Alert 0 :Alert signal from eSPI slave to the PCH. If only a single Slave is connected, the eSPI Compatibility Specification requires that the Slave must operate with in-band Alert# signaling in order to free up the GPIO pin required for the discrete Alert# pin. |
GPP_A11 / ESPI_ALERT1# | I | eSPI Alert 1 : Alert signal from eSPI slave to the PCH. If only a single Slave is connected, the eSPI Compatibility Spec requires that the Slave must operate with in-band Alert# signaling in order to free up the GPIO pin required for the discrete Alert# pin. |
