6.4.3.4
The ACCERR flag will be set during a command write sequence if any of the illegal operations below are
performed. Such operations will cause the command sequence to immediately abort.
The PVIOL flag will be set during a command write sequence after the longword write to the CFM array
if any of the illegal operations below are performed. Such operations will cause the command sequence to
immediately abort.
If a Flash physical block is read during a program or erase operation on that block (CFMUSTAT bit CCIF
= 0), the read will return non-valid data and the ACCERR flag will not be set.
6.4.4
If a command is active (CCIF = 0) when the MCU enters stop mode, the command sequence monitor
performs the following:

1. Writing to the CFM array before initializing CFMCLKD.
2. Writing to the CFM array while in emulation mode.
3. Writing a byte or a word to the CFM array. Only 32-bit longword programming is allowed.
4. Writing to the CFM array while CBEIF is not set.
5. Writing an invalid user command to the CFMCMD.
6. Writing to any CFM other than CFMCMD after writing a longword to the CFM array.
7. Writing a second command to CFMCMD before executing the previously written command.
8. Writing to any CFM register other than CFMUSTAT (to clear CBEIF) after writing to the
9. Entering stop mode while a program or erase command is in progress.

Stop Mode
Flash User Mode Illegal Operations
The state of any longword(s) being programmed or any erase pages/physical
blocks being erased is not guaranteed if the MCU enters stop mode with a
command in progress.
Active commands are immediately aborted when the MCU enters stop
mode. Do not execute the STOP instruction during program and erase
operations.
