NOTES:
RCR.15 = READ MODE (RM)
0 = Synchronous Burst Reads Enabled
1 = Page-Mode Reads Enabled (Default)
Read mode configuration effects reads from
main blocks. Parameter block, status register,
and identifier reads support single read cycles.
RCR.14 = RESERVED FOR FUTURE
ENHANCEMENTS (R)
These bits are reserved for future use. Set
these bits to
“0.”
RCR.13
–11 = FREQUENCY CONFIGURATION (FC2-0)
001 = Code 1 reserved for future use
010 = Code 2
011 = Code 3
100 = Code 4
101 = Code 5
110 = Code 6
See Section 4.9.2 for information about the
frequency configuration and its effect on the
initial read.
Undocumented combinations of bits
RCR.14–11 are reserved by Intel Corporation
for future implementations and should not be
used.
RCR.10 = RESERVED FOR FUTURE
ENHANCEMENTS (R)
These bits are reserved for future use. Set
these bits to “0.”
RCR.9 = DATA OUTPUT CONFIGURATION (DOC)
0 = Hold Data for One Clock
1 = Hold Data for Two Clocks
Undocumented combinations of bits RCR.10–9
are reserved by Intel Corporation for future
implementations and should not be used.
RCR.8 = WAIT CONFIGURATION (WC)
0 = WAIT# Asserted During Delay
1 = WAIT# Asserted One Data Cycle Before Delay
RCR.7 = BURST SEQUENCE (BS)
0 = Intel Burst Order
1 = Linear Burst Order
RCR.6 = CLOCK CONFIGURATION (CC)
0 = Burst Starts and Data Output on Falling
Clock Edge
1 = Burst Starts and Data Output on Rising
Clock Edge
RCR.5–3 = RESERVED FOR FUTURE
ENHANCEMENTS (R)
These bits are reserved for future use. Set
these bits to “0.”
RCR.2–0 = BURST LENGTH (BL2–0)
001 = 4 Word Burst
010 = 8 Word Burst
111 = Continuous Burst
In the asynchronous page mode, the burst
length always equals four words.
Undocumented combinations of bits RCR.2–0
are reserved by Intel Corporation for future
implementations and should not be used
