config FLASH_SIMULATOR_UNALIGNED_READ
	bool "Allow read access to be unaligned"
	default y
	help
	 If selected, the reading operation does not check if access is aligned.
	 Disable this option only if you want to simulate
	 a specific FLASH interface that requires aligned read access.

config FLASH_SIMULATOR_DOUBLE_WRITES
	bool "Allow program units to be programmed more than once"
	help
	 If selected, writing to a non-erased program unit will succeed, otherwise, it will return an error.
	 Keep in mind that write operations can only pull bits to zero, regardless.

config FLASH_SIMULATOR_ERASE_PROTECT
	bool "Enable erase protection on write protection"
	default y
	help
	 If selected, turning on write protection will also prevent erasing.

	bool "Enable hardware timing simulation"

config FLASH_SIMULATOR_STAT_PAGE_COUNT
	int "Pages under statistic"
	range 1 256
	default 256
	help
	  Only up to this number of beginning pages will be tracked
	  while catching dedicated flash operations and thresholds.
	  This number is not automatic because implementation uses
	  UNTIL_REPEAT() macro, which is limited to take explicitly
	  number of iterations.
	  This is why it's not possible to calculate the number of pages with
	  preprocessor using DT properties.
