* Name: stm32_flash_user_optbytes
*
* Description:
* Modify the contents of the user option bytes (USR OPT) on the flash.
* This does not set OBL_LAUNCH so new options take effect only after
* next power reset.
*
* Input Parameters:
* clrbits - Bits in the option bytes to be cleared
* setbits - Bits in the option bytes to be set
*
* Returned Value:
* Option bytes after operation is completed
