◆ MaskRom mode
The MaskRom mode is used to repair the system when the bootloader is
damaged. In general, you don't need to go into MaskRom mode, only if the
bootloader check fails (the IDR block is not read or the bootloader is
corrupted), the BootRom code enters MaskRom mode. At this point, the
BootRom code waits for the host to pass the bootloader code through the
USB port, then load and run it.
