REGISTERS
There are five types of registers available on the
SST49LF00xC, the multi-byte Read/Write configuration
registers, General Purpose Inputs registers, Block Locking
registers, Security ID register, and the JEDEC ID registers.
These registers appear at their respective address location
in the 4 GByte system memory map. Unused register loca-
tions will read as 00H. Any attempt to read or write any reg-
ister during an internal Write operation will be ignored.
Read or write access to the register during an internal Pro-
gram/Erase operation will be completed as follows:
Multi-byte Read/Write Configuration registers,
General Purpose Inputs register, and Block Lock-
ing registers can be accessed normally
Security ID register and the JEDEC ID registers
can not be accessed (reading these registers will
return unused register data 00H).
Multi-Byte Read/Write Configuration Reg-
isters (Firmware Memory Cycle)
The multi-byte read/write configuration (MBR) registers are
four 8-bit read-only registers located at addresses
FFBC0005-FFBC0008 for boot configured device (see
Table 13). These registers are accessible using Firmware
Memory Read cycle only. These registers contain informa-
tion about multi-byte read and write access sizes that will
be accepted for Firmware Memory multi-byte Read com-
mands. The registers are not available in AAI mode.
In case of multi-byte Firmware Memory register reads, the
device will return register data for the addressed register
until the command finishes, or is aborted.
General Purpose Inputs Register
The General Purpose Inputs register (GPI_REG) passes
the state of GPI[4:0] pins on the SST49LF00xC. It is rec-
ommended that the GPI[4:0] pins be in the desired state
before LFRAME# is brought low for the beginning of the
bus cycle, and remain in that state until the end of the cycle.
There is no default value since this is a pass-through regis-
ter. The GPI_REG register for the boot device appears at
FFBC0100H in the 4 GByte system memory map, and will
appear elsewhere if the device is not the boot device (see
Table 12). This register is not available to be read when the
device is in an Erase/Program operation. In case of multi-
byte Firmware Memory cycle register reads, the device will
return register data for the addressed register until the com-
mand finishes, or is aborted.

Register Address1
1. Address shown in this column is for boot device only.
Address locations should appear elsewhere in the 4
