state of the SGFM will be determined by the FLASH security word,
which, after being erased, will read 0xffff_ffff, thus unsecuring the
module.
The SGFM array is not accessible for any operations via the address and
data buses during reset. If a reset occurs while any command is in
progress that command will immediately abort. The state of any word
being programmed or any erase pages/physical blocks being erased is
not guaranteed.
The SGFM module can request an interrupt when all commands are
completed or when the address, data, and command buffers are empty.
Figure 10-19
the CBEIE and CCIE bits as well as the register bank select signals to
enable interrupt requests. By taking into account the selected register
bank, false interrupt requests are not generated when the command
buffer is empty in an unselected register bank.
