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 7.1 on page 55 , 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
The S29GL-S family has uniform sector architecture with a sector size of 128 kB. Table 2.1 to Table 2.4 shows the sector
architecture of the four devices.
