341 	 *  Notify the CPU2 that some flash erase activity may be executed  in flash_stm32_block_erase_loop()
342 	 *  On reception of this command, the CPU2 enables the BLE timing  in flash_stm32_block_erase_loop()
346 	 *  The CPU2 will prevent all flash activity (write or erase) in all  in flash_stm32_block_erase_loop()
362 	 *  Notify the CPU2 there will be no request anymore to erase the flash  in flash_stm32_block_erase_loop()
363 	 *  On reception of this command, the CPU2 disables the BLE timing  in flash_stm32_block_erase_loop()
