Data Retention
Two devices cannot drive the memory bus at the same time.
To place the SRAM into data retention mode, lower the S-V
Modes
Read
The flash memory device provides four read modes:
These flash memory read modes do not depend on the F-V
or after exit from reset, the flash memory device automatically defaults to read array mode. F-CE#
and F-OE# must be asserted to obtain data from the flash memory device.
The SRAM provides only one read mode. S-CS1#, S-CS2, and S-OE# must be asserted to obtain
data from the SRAM device. See
Intel Advanced+ Boot Block Flash Memory SCSP Bus Operations
Output Disable
When F-OE# and S-OE# are deasserted, the SCSP output signals are placed in a high-impedance
state.
