Operation Timing
R
A Low-to-High transition on the CSB input completes the command and the Flash then
erases the selected block of 8 pages. The erase operation is internally self-timed and
completes in the time shown in
sheet. During this time, the
whether the Sector Erase operation is in progress or whether it has completed.
Table 5-13: Sector Erase Time
While the Sector Erase operation is in progress, the FPGA can access any other portion of
the ISF memory, including any of the following commands.
•
