0.3.2 Reset Confirmation Packet
A reset confirmation packet is transmitted to acknowledge the
reception of a reset request packet after the reset procedures
have been performed (see the previous paragraph). However, if a
reset request packet has been sent and a reset request packet
received the transmission of a reset confirmation packet is not

packet as a reset confirmation packet. The format of a reset
confirmation packet is as follows:
