Notes:
1. Read timing characteristics during read/write operations are the same as during read-only operations. Refer to AC
Characteristics for Read Only operations.
2. Maximum pulse widths not required because the on-chip program/erase stop timer will terminate the pulse widths internally
on the device.
3. Chip-Enable Controlled Writes: Write operations are driven by the valid combination of Chip-Enable and Write-Enable. In
systems where Chip-Enable defines the Write Pulse Width (within a longer Write-Enable timing waveform) all setup, hold and
inactive Write-Enable times should be measured relative to the Chip-Enable waveform.
4. Not 100% tested.
