WRITE PROTECTION
The SMM605 powers up into a write protected mode.
Writing a code to the volatile write protection register
can disable the write protection. The write protection
register is located at address 87
HEX
of slave address
1001
BIN
.
Writing 0101
BIN
to bits [7:4] of the write protection
register allow writes to the general-purpose memory
while writing 0101
BIN
to bits [3:0] allow writes to the
configuration registers. The write protection can re-
enable by writing other codes (not 0101
BIN
) to the write
protection register. Writing to the write protection
register is shown in Figure 11.
CONFIGURATION REGISTERS
The majority of the configuration registers are grouped
with the general-purpose memory located at either
slave address 1010
BIN
or 1011
BIN
. The bus address
bits, A[1:0], used to differentiate the general-purpose
memory from the configuration registers are set to
11
BIN
. Bus address bit A[2] can be programmed as
either 0 or biased by the A2 pin.
Two additional configuration registers are located at
addresses 83
HEX
and 84
HEX
of slave address 1001
BIN
.
Writing and reading the configuration registers is
shown in Figures 14 and 16.
Note: Configuration writes or reads of registers 00
HEX
to 0F
HEX
should not be performed while the SMM605 is
margining.
GENERAL-PURPOSE MEMORY
The 4k-bit general-purpose memory is located at
either slave address 1010
BIN
or 1011
BIN
. The bus
address bits, A[1:0], used to differentiate the general-
purpose memory from the configuration registers are
set to 00
BIN
for the first 2k-bits and 01
BIN
for the second
2k-bits. Bus address bit A[2] can be programmed as
either 0 or biased by the A2 pin.
The word address must be set each time the memory
is accessed. Memory writes and reads are shown in
Figures 17, 18 and 19.
COMMAND AND STATUS REGISTERS
The command and status registers are located at
slave address 1001
BIN
. Writes and reads of the
command and status registers are shown in Figures
20 and 21.
GRAPHICAL USER INTERFACE (GUI)
Device configuration utilizing the Windows based
SMM605 graphical user interface (GUI) is highly
recommended. The software is available from the
Summit website (
www.summitmicro.com
). Using the
GUI in conjunction with this datasheet and application
note 40 simplifies the process of device prototyping
and the interaction of the various functional blocks. A
programming Dongle (SMX3200) is available from
Summit to communicate with the SMM605. The
Dongle connects directly to the parallel port of a PC
and programs the device through a cable using the I
C
bus protocol.
