The eSPI controller configuration is used by the eSPI boot ROM software. After the boot from eSPI has
finished, the user can change this configuration for other uses of the eSPI interface.
The eSPI controller is configured to operate in master mode. The eSPI chip select 0 (SPI_CS[0]) must be
connected to the EEPROM CS and selectively enables the EEPROM.
Figure 4-13
The eSPI controller is configured by the on-chip ROM code. The controller is configured as follows:

Field CI0 CP0 REV0 DIV160
The ROM code will initially use the eSPI controller to generate standard read instruction code 0x03
followed by a 3-byte address for every non-sequential read operation (reading from a location which is not
sequential to the last byte read). For sequential read operation, toggling the eSPI clock will cause the eSPI
EEPROM to present the content of the next address location. The serial EEPROM must have an eSPI
compatible interface with read instruction code 0x03 followed by a 2- or 3-byte address.

Data is shifted out data on SPIMOSI during the falling edge of SPI_CLK. It samples data in from
SPIMISO during the rising edge of SPI_CLK.
The clock is low when the line is idle.
It uses 8-bit length characters.
The platform clock is divided by 256. For example, when the platform clock is configured to
533 MHz, the SPI_CLK will run at 2.08 MHz. (Note that frequency setting can be changed by
using the CF control word, as explained in the
The MSB is sent and received first.
