13.4.4
Only the operations marked ‘OK’ in
Flash and Data Flash blocks. Some operations cannot be executed simultaneously because certain
hardware resources are shared by the two memories. The priority has been placed on permitting Program
Flash reads while program and erase operations execute on the Data Flash, providing read (P-Flash) while
write (D-Flash) functionality.
13.4.5
This section provides details of all available Flash commands launched by a command write sequence. The
ACCERR bit in the FSTAT register will be set during the command write sequence if any of the following
illegal steps are performed, causing the command not to be processed by the Memory Controller:
