The Command Register

Field
Range
Initial
Value
Description
SRST
[0]
0
Software Reset.
If '1,' this bit resets the device, with the same effect as the hardware
reset. Internally, it generates a reset pulse lasting for eight CLK cycles. This bit
automatically resets to a '0' the reset cycle has completed.
DEVE
[1]
0
Device Enable.
If '0,' it keeps the SRAM Bus (SADR, WE_L, CE_L, OE_L, and
ALE_L), SSF, and SSV signals in 3-state condition and forces the cascade interface
output signals LHO[1:0] and BHO[2:0] to '0.' It also keeps the DQ Bus in input mode.
The purpose of this bit is to make sure that there are no bus contentions when the
devices power up in the system.
TLSZ
[3:2]
01
Table Size.
The host ASIC must program this field to configure the chips into a table
of a certain size. This field affects the pipeline latency of the SEARCH and LEARN
operations as well as the READ and WRITE accesses to the SRAM (SADR[23:0],
CE_L, OE_L, WE_L, ALE_L, SSV, SSF, and ACK). Once programmed, the search
latency stays constant.
Latency # CLK Cycles
with HIGH_SPEED low
00: 1 device
4
01: 2-8 devices
5
10: 9-31 devices
6
11: Reserved
Latency # CLK Cycles
with HIGH_SPEED high
00: Not supported
01: 1 devices

10: 2-31 devices
6

HLAT
[6:4]
000
Latency of Hit Signals.
This field adds latency to the SSF and SSV signals during
SEARCH, and ACK signal during SRAM READ access by the following number of
CLK cycles.
000: 0
100: 4
001: 1
101: 5
010: 2
110: 6
011: 3
111: 7
LDEV
[7]
0
Last device in the cascade.
When set, this is the last device in the depth-cascaded
table and is the default driver for the SSF and SSV signals.
In the event of a search failure, the device with this bit set drives the hit signals as
follows:
SSF = 0, SSV = 1
During non-search cycles, the device with this bit set drives the signals as follows:
SSF = 0, SSV = 0
