29.3.2.10 User Test 0 register (UT0)
The User Test 0 register feature gives the user of the Flash Memory module the ability to
perform test features on the flash.
The User Test 0 register allows control of the way the flash content check is performed. Bits
MRE, MRV and AIS of the User Test 0 register are not accessible when MCR[DONE] or
UT0[AID] are low. Reading returns indeterminate data while writing has no effect.

Field
User Test Enable (Read/Clear)
This status bit gives indication when User Test is enabled.
All bits in UT0 and UM0–UM9 are locked when this bit is '0'.
0
This bit is not writable to a '1', but may be cleared. The reset value is '0'.
UTE
To set UTE, write the password 0xF9F99999 to the UT0 register. The UTE password is only
accepted if PGM=0 and ERS=0 (Program and Erase are not being requested).
UTE can only be cleared if AID=1, MRE=0 and AIE=0. While clearing UTE, writes to set AIE
or MRE are ignored.
Single Bit Correction Enable (Read/Clear)
This bit, when high, enables to flag the information about any eventual ECC Single Bit
1
Correction in the flash array (MCR.SBC and ADR). This is true in read mode and in Array
Integrity Check.
SBCE
SBCE also is used as an Enable for interrupt signals created by the embedded flash memory.
ECC corrections that occur when SBCE is cleared are not logged.
