8.6 Power down handling：
1）The power cable is combined with 4- wire（red-yellow-2 black） ，12V-red/yellow，GND-black，
the yellow-black in middle set is prepared for backup power supply，connecting to back-up
capacitor for card ejecting when power down；
2）Once main power down，there is a backup power for preparing work，the ICRW will start
to run its power down mode after 1 second，if the card is inside of the ICRW, eject card
or not decided by set of PD parameter; ICRW responses negative to any command before the
power supply recovered（error word“power down protected state”） ；
3）If the main power is recovered (≥11V)，the ICRW returns to previous state (before power
down) by executing reset command.
8.7 Error handling
Once ICRW occupied with the error of blocks，it’s necessary to clear the error sign by sending
the reset command, after that it’s possible to execute other commands.(The details referred
to protocol)
