COMMAND CODES AND PARAMETERS
A master device, such as an ASIC controller, is-
sues commands to the M7040N using the Com-
mand Valid CMDV signal and the CMD Bus. The
following subsections describe the functions of the
commands.
Command Codes
The M7040N implements four basic commands
shown in Table 17. The Command Code must be
presented to CMD[1:0] while keeping the com-
mand valid (CMDV) signal high for two CLK2X cy-
cles. These two CLK2X cycles are designated as
Cycle A
and
Cycle B
when the CLK_MODE pin
is low. In CLK2X mode, the controller ASIC must
align the instructions with the PHS_L signal. The
command code must be presented to CMD[1:0]
while keeping the CMDV signal high for one
CLK1X cycle when the CLK_MODE pin is high. In
CLK1X mode the high phase of the CLK1X is des-
ignated as Cycle A and the low phase of the
CLK1X is designated as Cycle B. The CMD[10:2]
field passes the parameters of the command in
Cycles A and B.
Commands and Command Parameters
Table 18, page 31 lists the CMD bus fields that
contain the M7040N command parameters as well
as their respective cycles.

Command
Description
00
READ
Reads one of the following: data array, mask array, device registers, or external
SRAM.
01
WRITE
Writes one of the following: data array, mask array, device registers, or external
SRAM.
10
SEARCH
Searches the data array for a desired pattern using the specified register from the
global mask register array and local mask associated with each data cell.
11
LEARN
The device has internal storage for up to 16 comparands that it can learn. The
device controller can insert these entries at the next free address (as specified by
the NFA register) using the LEARN Instruction.
