Description
Program-Verify
When this bit is set to 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 SWE=1 and ESU=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 SWE=1 and PSU=1, the
flash memory changes to program mode. When it is
cleared to 0, program mode is cancelled.
Description
Flash Memory Error
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 7.5.3, Error Protection, for details.
Reserved
These bits are always read as 0.
