Registers
There is one register available on the SST49LF020. The
General Purpose Inputs Register. This register appears
at its respective address location in the 4 GByte system
memory map.
General Purpose Inputs Register
The GPI_REG (General Purpose Inputs Register)
passes the state of GPI[4:0] pins at power-up on the
SST49LF020. It is recommended that the GPI[4:0] pins
be in the desired state before LFRAME# is brought low
for the beginning of the next bus cycle, and remain in that
state until the end of the cycle. There is no default value
since this is a pass-through register. The GPI register
appears at FFBC0100H in the 4 GBytes system memory
map. See General Purpose Inputs Register table for the
GPI_REG bits and function.
CE#
The CE# pin, enables and disables the SST49LF020, con-
trolling read and write access of the device. To enable the
SST49LF020, the CE# pin must be driven low one cycle
prior to LFRAME# being driven low. For write (erase or pro-
gram) cycles, the CE# pin must remain low during the inter-
nal programming. When CE# is high, the SST49LF020 is
placed in low-power standby-mode.
LFRAME#
The LFRAME# signifies the start of a frame or the termina-
tion of a broken frame. Asserting LFRAME# for one or
more clock cycle and driving a valid START value on
LAD[3:0] will initiate device operation. The device enters
standby mode when LFRAME# and CE# are high and no
internal operations is in progress.
Abort Mechanism
If LFRAME# is driven low for one or more clock cycles dur-
ing a LPC cycle, the cycle will be terminated and the device
will wait for the ABORT command. The host must drive the
LAD[3:0] with ‘1111b’ (ABORT command) to return the
device to the ready mode. If abort occurs during the inter-
nal write cycle, the data may be incorrectly programmed or
erased. It is required to wait for the Write operation to com-
plete prior to initiation of the abort command. It is recom-
mended to check the write status with Data# Polling (DQ7)
or Toggle Bit (DQ6) pins. One other option is to wait for the
fixed write time to expire.
