10.4.5 PAGE SIZE Bit

The PAGE SIZE bit indicates whether the buffer size and the page size of the main memory array is configured for

the “power of 2” binary page size (512 bytes) or the standard DataFlash page size (528 bytes).

10.4.6 EPE Bit

The EPE bit indicates whether the last erase or program operation completed successfully or not. If at least one

byte during the erase or program operation did not erase or program properly, then the EPE bit is set to the logic 1

state. The EPE bit is not set if an erase or program operation aborts for any reason, such as an attempt to erase or

program a protected region or a locked down sector or an attempt to erase or program a suspended sector. The

EPE bit is updated after every erase and program operation.

10.4.7 SLE Bit

The SLE bit indicates whether or not the Sector Lockdown command is enabled or disabled. If the SLE bit is a logic

1, then the Sector Lockdown command is still enabled and sectors can be locked down. If the SLE bit is a logic 0,

then the Sector Lockdown command has been disabled and no further sectors can be locked down.

10.4.8 PS2 Bit

The PS2 bit indicates if a program operation has been suspended while using Buffer 2. If the PS2 bit is a logic 1,

then a program operation has been suspended while Buffer 2 was being used, and any command attempts that

can modify the contents of Buffer 2 are ignored.

10.4.9 PS1 Bit

The PS1 bit indicates if a program operation has been suspended while using Buffer 1. If the PS1 bit is a logic 1,

then a program operation has been suspended while Buffer 1 was being used, and any command attempts that

can modify the contents of Buffer 1 are ignored.

10.4.10 The ES bit

The ES bit indicates whether or not an erase has been suspended. If the ES bit is a logic 1, then an erase

operation (page, block, sector, or chip) has been suspended.
