NOTES:  
1. L = VIL, H = VIH, X = Don’t Care.  
2. When ADV/LD signal is sampled high, the internal burst counter is incremented. The R/W signal is ignored when the counter is advanced. Therefore the nature of  
the burst cycle (Read or Write) is determined by the status of the R/W signal when the first address is loaded at the beginning of the burst cycle.  
3. Deselect cycle is initiated when either (CE1, or CE2 is sampled high or CE2 is sampled low) and ADV/LD is sampled low at rising edge of clock. The data bus will  
tri-state two cycles after deselect is initiated.  
4. When CEN is sampled high at the rising edge of clock, that clock edge is blocked from propogating through the part. The state of all the internal registers and the I/  
Os remains unchanged.  
5. To select the chip requires CE1 = L, CE2 = L, CE2 = H on these chip enables. Chip is deselected if either one of the chip enables is false.  
6. Device Outputs are ensured to be in High-Z after the first rising edge of clock upon power-up.  
7. Q - Data read from the device, D - data written to the device.
