CFG = 1010101010101010, HLAT = 000, TLSZ = 01, LRAM = 1, LDEV = 1.
Note: |(LHI[6:0]) stands for the boolean ‘OR’ of the entire bus LHI[6:0].
Note: Each bit in LHO[1:0] is the same logical signal.
• Cycle A: The host ASIC drives the CMDV high and applies Search command code (10) on CMD[1:0] signals. {CMD[10],
• Cycle B: The host ASIC continues to drive the CMDV high and applies Search command code (10) on CMD[1:0]. The DQ[71:0]
• Cycle C: The host ASIC drives the CMDV high and applies Search command code (10) on CMD[1:0] signals. {CMD[10],
CMD[5:3]} signals must be driven with the index to the GMR pair used for bits [287:144] of the data being searched in this
operation. DQ[71:0] must be driven with the 72-bit data ([287:216]) to be compared against all locations 0 in the four-word 72-
bit page. The CMD[2] signal must be driven to logic 1.

CMD[5:3]} signals must be driven with the index to the GMR pair used for bits [143:0] of the data being searched. CMD[8:6]
signals must be driven with the bits that will be driven on SADR[23:21] by this device if it has a hit. DQ[71:0] must be driven
