Switching Waveforms
Read Cycle 1 (Address Transition Controlled)
[16, 17]
Read Cycle No. 2 (OE Controlled)
[17, 18]
Notes:
16.The device is continuously selected. OE, CE = V
IL
, BHE and/or BLE = V
IL
.
17.WE is HIGH for read cycle.
18.Address valid prior to or coincident with CE and BHE, BLE transition LOW.
