Data Polling Waveforms
Notes: 1. These parameters are characterized and not 100% tested.
2. See t
OE
spec in AC Read Characteristics.
Toggle Bit Waveforms
(1)(2)(3)
Notes: 1. Toggling either OE or CE or both OE and CE will operate toggle bit. The t
OEHP
specification must be met by the toggling
input(s).
2. Beginning and ending state of I/O6 will vary.
3. Any address location may be used but the address should not vary.
