MGSTAT0
Memory Controller Command Completion Status Flag
The MGSTAT0 status flag is set if an error is detected during execution of a flash command or during the
flash reset sequence. As a status flag, this field cannot (and need not) be cleared by the user like the other
error flags in this register.
The value of the MGSTAT0 bit for "command-N" is valid only at the end of the "command-N" execution
when CCIF=1 and before the next command has been launched. At some point during the execution of
"command-N+1," the previous result is discarded and any previous error is cleared.
29.3.3.2 Flash Configuration Register (FTFA_FCNFG)
This register provides information on the current functional state of the flash memory
module.
The erase control bits (ERSAREQ and ERSSUSP) have write restrictions. The
unassigned bits read as noted and are not writable.

Field Description
7
CCIE
Command Complete Interrupt Enable
Controls interrupt generation when a flash command completes.
0 Command complete interrupt disabled
1 Command complete interrupt enabled. An interrupt request is generated whenever the FSTAT[CCIF]
flag is set.
6
RDCOLLIE
Read Collision Error Interrupt Enable
Controls interrupt generation when a flash memory read collision error occurs.
0 Read collision error interrupt disabled
1 Read collision error interrupt enabled. An interrupt request is generated whenever a flash memory
read collision error is detected (see the description of FSTAT[RDCOLERR]).
