Data Sheet
While in EA mode, only a Program / Erase suspend command or the Status Register Read command will be
accepted. All other commands are ignored. Thus, no other ASO may be entered from the EA mode.
When an Embedded Algorithm is suspended, the Data Polling ASO is visible until the device has suspended
the EA. When the EA is suspended the Data Polling ASO is exited and Flash Array data is available. The
Data Polling ASO is reentered when the suspended EA is resumed, until the EA is again suspended or
finished. When an Embedded Algorithm is completed, the Data Polling ASO is exited and the device goes to
the previous (calling) mode (from which the Embedded Algorithm was started).
In ASO mode, one of the remaining overlay address spaces is entered (overlaid on the main Flash Array
address map). Only one ASO may be entered at any one time. Commands to the device affect the currently
entered ASO. Only certain commands are valid for each ASO. These are listed in the Table 6.1 on page 57,
in each ASO related section of the table.
The following ASOs have non-volatile data that may be programmed to change 1’s to 0’s:
 Secure Silicon Region
 Lock Register
 Persistent Protection Bits (PPB)
 Password
 Only the PPB ASO has non-volatile data that may be erased to change 0’s to 1’s
When a program or erase command is issued while one of the non-volatile ASOs is entered, the EA operates
on the ASO. The ASO is not readable while the EA is active. When the EA is completed the ASO remains
entered and is again readable. Suspend and Resume commands are ignored during an EA operating on any
of these ASOs.
2.1 Flash Memory Array
