Parameter Sector Erase (P4E, P8E)
The Parameter Sector Erase (P4E, P8E) command sets all bits at all addresses within a specified sector to a
logic 1 (FFh). A WREN command is required prior to writing the Parameter Sector Erase commands.
The host system must drive CS# low, and then write the P4E or P8E command, plus three address bytes on
SI. Any address within the sector (see
CS# must be driven low for the entire duration of the P4E/P8E sequence. The command sequence is shown
in
The host system must drive CS# high after the device has latched the 24th bit of the P4E/P8E address,
otherwise the device does not execute the command. The parameter sector erase operation begins as soon
as CS# is driven high. The device internally controls the timing of the operation, which requires a period of
t
parameter sector erase operation is in progress. The WIP bit is 1 during the P4E/P8E operation, and is 0
when the operation is completed. The device internally resets the Write Enable Latch to 0 before the
operation completes (the exact timing is not specified).
A Parameter Sector Erase (P4E, P8E) instruction applied to a sector that has been Write Protected through
the Block Protect Bits will not be executed.
The Parameter Sector Erase Command (P8E) erases two of the 4 KB Sectors in selected address space.
The Parameter Sector Erase Command (P8E) erases two sequential 4 KB Parameter Sectors in the selected
address space. The address LSB is disregarded so that two sequential 4 KB Parameter Sectors are erased.
The 24 Bit Address is any location within the first Sector to be erased (n), and the next sequential 4 KB
Parameter Sector will also be erased (n+1). The 4 KB parameter Sector will only be erased properly if n or
n+1 is a valid 4 KB parameter Sector. i.e. If n is not a valid 4K parameter Sector, then it will not be erased. If
n+1 is not a valid 4 KB parameter Sector, then it will not be erased.
