Note
table must be programmed with LRAM = 1 and LDEV = 1 (device number 3 in this case).
Figure 10-25 shows the timing diagram for a Search command in the 144-bit-configured table of four devices for device number 0.
Figure 10-26 shows the timing diagram for a Search command in the 144-bit-configured table consisting of four devices for device
number 1. Figure 10-27 shows the timing diagram for a Search command in the 144-bit configured table consisting of four devices
for device number 3 (the last device in this specific table). For these timing diagrams, the four 144-bit searches are performed
sequentially, and the following Hit/Miss assumptions are made (see Table 10-16).
