Description
Erase-Verify
When this bit is set to 1 while the FEW and SWE bits
are 1, the flash memory changes to erase-verify
mode. When it is cleared to 0, erase-verify mode is
cancelled.
Program-Verify
When this bit is set to 1 while the FEW and SWE bits
are 1, the flash memory changes to program-verify
mode. When it is cleared to 0, program-verify mode is
cancelled.
Erase
When this bit is set to 1 while the FEW, SWE and
ESU bits are 1, the flash memory changes to erase
mode. When it is cleared to 0, erase mode is
cancelled.
Program
When this bit is set to 1 while the FEW, SWE and
PSU bits are 1, the flash memory changes to
program mode. When it is cleared to 0, program
mode is cancelled.
Description
Indicates that an error has occurred during an
operation on flash memory (programming or erasing).
When FLER is set to 1, flash memory goes to the
error-protection state.
See section 19.9.3, Error Protection, for details.
Reserved
These bits are always read as 0.
