Table 5-2: Page Addressing Summary
Table 5-3: Page Address, Default Addressing Mode
A Low-to-High transition on the CSB input completes the command and the Flash then
erases the selected page. The erase operation is internally self-timed and completes in the
time shown in
time, the
operation is in progress or whether it has completed.
