9.4.10 The ES bit
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).
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 will be set to the Logic 1 state.
The EPE bit will not be 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.
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.
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 would modify
the contents of Buffer 2 will be ignored.
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 would modify
the contents of Buffer 1 will be ignored.
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.
