enhanced Serial Peripheral Interface (eSPI)
The P5040/P5020 has an eSPI Master Controller used to communicate with various peripherals.
•
Two SPI FLASH support 24-bit address and SPI Modes 0, 3.
•
Use Chip Select 0 or 1 with S25FL129P0XNFI001 FLASH if CVDD=3.3 V.
•
Use Chip Select 2 with 25AA1024T-I/SM FLASH for all CVDD voltages (1.8, 2.5, or 3.3 V).
•
Chip Select 3 is reserved for 1588 Riser Card.
