Review comment:
Is this correct test on a write ?
```
SNECCERR1: Bank 1 single correction error flag
SNECCERR1 flag is raised when an ECC single correction error occurs during a
read
operation from bank 1. An interrupt is generated if SNECCERRIE1 is set to 1.
Writing 1 to
CLR_SNECCERR1 bit in FLASH_CCR1 register clears SNECCERR1.
0: no ECC single correction error occurs on bank 1
1: ECC single correction error occurs on bank 1
```
Or should this be checked on the read?
