• LHI_1_L signals are active LOW while LHI_0 are active HIGH.
The MultiSearch Enable (MSE) bit in the Command Register must be set HIGH when the Command Register is programmed.
The same with the Enhanced Mode (EMODE) bit. The following are the rest of the parameters programmed into the eight devices.
• First seven devices (devices 0–6): NES = 00 (binary) for each block in each device, TLSZ = 01 (binary), HLAT = 001 (binary),
LRAM = 0 (binary), and LDEV = 0 (binary).
• Eighth device (device 7): NES = 00 (binary) for each block in each device, TLSZ = 01 (binary), HLAT = 001 (binary), LRAM =
1 (binary), and LDEV = 1 (binary).
For a single-device configuration, the parameters are the same as device 7. BHI[2:0] and LHI[6:0] should be tied to ground.
The following three figures show the response of 3 of the 8 devices having a hit at different time according to a Hit/Miss assumption
shown below in Table 6-7. For these timing diagrams, five 72-bit searches are performed sequentially. Figure 6-15 shows the
timing diagram for a Search command in the 72-bit-configured table of eight devices for device number 0. Figure 6-16 and
Figure 6-17 shows the same for device number 1 and number 7 (the last device in this specific table) respectively.
