Data read back from this register is not defined and therefore must be ignored. Reading from
this register makes no effect on LAN bypass function. All data in this register will be cleared
when system is turned off. If you still want to use power on LAN bypass function, turn on the
system and make sure to rewrite the register. Otherwise, if you
don’t rewrite the register, the
status will be kept on power off bypass state.
