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. 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.
