Comments
LFRAME# must be active (low) for the part to respond.
Only the last start field (before LFRAME# transitions
high) should be recognized.
Indicates the type of cycle. Bits 3:2 must be “01b” for
memory cycle. Bit 1 indicates the type of transfer “1”
for Write. Bit 0 is reserved.
Address Phase for Memory Cycle. LPC protocol sup-
ports a 32-bit address phase. YYYY is one nibble of
the entire address. Addresses are transferred most-
significant nibble first. See Table 3 for address bits def-
inition and Table 4 for valid memory address range.
This field is the least-significant nibble of the data byte.
This field is the most-significant nibble of the data byte.
In this clock cycle, the host has driven the bus to all ‘1’s
and then floats the bus. This is the first part of the bus
“turnaround cycle.”
The SST49LF080A takes control of the bus during this
cycle.
The SST49LF080A outputs the values 0000, indicat-
ing that it has received data or a flash command.
In this clock cycle, the SST49LF080A has driven the
bus to all ‘1’s and then floats the bus. This is the first
part of the bus “turnaround cycle.”
Host resumes control of the bus during this cycle.
