+If you use OTP (One-Time Programmable) memory define it as a second bank
+as per the following example.
+@example
+flash bank $_FLASHNAME stm32f2x 0x1FFF7800 0 0 0 $_TARGETNAME

+@deffn Command {stm32f2x otp } num (@option{enable}|@option{disable}|@option{show})
+Enables or disables OTP write commands for bank @var{num}.
+The @var{num} parameter is a value shown by @command{flash banks}.

 Note that some devices have been found that have a flash size register that contains
 an invalid value, to workaround this issue you can override the probed value used by
 the flash driver.
