CFG = 1010101010101010, HLAT = 000, TLSZ = 10, LRAM = 1, LDEV = 1.
Note: |(BHI[2:0]) stands for the boolean ‘OR’ of the entire bus BHI[2:0].
Note: |(LHI[6:0]) stands for the boolean ‘OR’ for the entire bus LHI[6:0].
Note: Each bit in BHO[2:0] is the same logical signal.
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 (10) on CMD[1:0]. The DQ[71:0] is
CMD[5:3]} signals must be driven with the index to the GMR pair used for bits [287:144] of the data being searched. DQ[71:0]
must be driven with the 72-bit data ([287:216])to be compared to all locations 0 in the four 72-bits-word page. The CMD[2]
signal must be driven to logic 1.
