Command Complete Interrupt Flag — The CCIF flag indicates that a Flash command has completed. The
CCIF flag is cleared by writing a 1 to CCIF to launch a command and CCIF will stay low until command
completion or command violation.
0 Flash command in progress
1 Flash command has completed
Flash Access Error Flag — The ACCERR bit indicates an illegal access has occurred to the Flash memory
caused by either a violation of the command write sequence (see
command. While ACCERR is set, the CCIF flag cannot be cleared to launch a command. The ACCERR bit is
cleared by writing a 1 to ACCERR. Writing a 0 to the ACCERR bit has no effect on ACCERR.
0 No access error detected
1 Access error detected
Flash Protection Violation Flag —The FPVIOL bit indicates an attempt was made to program or erase an
address in a protected area of P-Flash or EEPROM memory during a command write sequence. The FPVIOL
bit is cleared by writing a 1 to FPVIOL. Writing a 0 to the FPVIOL bit has no effect on FPVIOL. While FPVIOL
is set, it is not possible to launch a command or start a command write sequence.
0 No protection violation detected
1 Protection violation detected
Memory Controller Busy Flag — The MGBUSY flag reflects the active state of the Memory Controller
0 Memory Controller is idle
1 Memory Controller is busy executing a Flash command (CCIF = 0)
Reserved Bit — This bit is reserved and always reads 0
Memory Controller Command Completion Status Flag — One or more MGSTAT flag bits are set if an error
is detected during execution of a Flash command or during the Flash reset sequence. See
