• FMR40 bit
• FMR41 bit
• FMR46 bit
The erase-suspend function is enabled by setting the FMR40 bit to “1” (valid).
In EW0 mode, the flash module goes to erase-suspend mode when the FMR41 bit is set to
“1”. In EW1 mode, the FMR41 bit is automatically set to “1” (erase-suspend requested) when
an enabled interrupt occurred, and then the flash module goes to erase-suspend mode.
The auto-erase operation restarts when the FMR41 bit is set to “0” (erase restart).
The FMR46 bit is set to “0”(disables reading) during auto-erase execution and set to “1”(en-
ables reading) during erase-suspend mode. Do not access to the flash memory when this bit
is set to “0”.
