(Default)

Default SFI Configuration on power-up or return

from deep power-down mode is 4, allowing

system boot from the 28F016XS at any

frequency up to the device's maximum

frequency. Undocumented combinations of

SFI2-SFI0 are reserved by Intel Corporation for

future implementations and should not be used.

DCC.0 = RY/BY# CONFIGURATION

(RB)

1 = Level Mode (Default)

Undocumented combinations of RB are reserved

by Intel Corporation for future implementations

and should not be used.

DCC.7–DCC.6, DCC.2–DCC.1 = RESERVED FOR FUTURE ENHANCEMENTS

These bits are reserved for future use. Set these bits to “0” when modifying the Device Configuration

Code.
