Flash Write Protect

Hello:

In Page_22 of AN11130:

''Note The very first time you program FLASH_NVWPAR or FLASH_NVAPR0 both the nonvolatile

and volatile part of the register are written.

At any later stage, any write to those registers will affect only the volatile part, which

will be restored with the content of the corresponding non-volatile part at the next

reset event.''

I have two questions.

1.Whether ''The very first time'' means the fist time after POWER_ON ?

2.How many times can I promgram the ''FLASH_NVWPAR or FLASH_NVAPR0'' the nonvolatile part of the register ?

Hi,

1) Yes, the very first time means the first time after POWER_ON.

2) There is no limitation on programming the non volatile part of the register.

Best regards,
