3. MaskRom mode¶

See startup mode for an introduction startup mode

MaskRom pattern is the last line of defense equipment burn out. Forced entry MaskRom involved hardware operation, have certain risk, so only in the equipment into the Loader mode, can try MaskRom mode.

Please read carefully and operate carefully!
