In FLASH_OPTR, both DBANK and DB1M are r/w and have no restrictions beside that PCROPA/B needs to be disabled.
For 1M device there are two(?) sensible settings
- DBANK=1, DB1M = 1 for 1Myte dual bank continous mode
- DBANK=0, DB1M = 0 for 1Myte single bank continous mode
Can for a 1 M byte device
- DBANK=1, DB1M = 0 get active? Evtentually with Flash from 0x08000000 to 0x0808000 and from 0x0810000 to 0x08180000?
What would DBANK=0, DB1M = 0 mean for a 1 MB device?
And does a DB1M have influence on a 2 MB device?
Some clarification welcome!

Hate to respond to a 2.5 year old thread, but I recently had the same question and received an answer so I am linking this thread to that one in case someone comes across this one day.
