WARNING:
NOTE:
The PVIOL flag will be set during a command write sequence after the
word write to the SGFM 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 (SGFMUSTAT bit CCIF = 0), the read will return non-valid
data and the ACCERR flag will not be set.
If a command is active (CCIF = 0) when the MCU enters stop mode, the
command sequence monitor will perform the following:
The state of any word(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.
