9.3.7 End Power Transfer Packet (WPC Header 0x02)

The WPC allows for a special command for the receiver to terminate power transfer from the transmitter termed End Power Transfer (EPT) packet. Table 9-4 specifies the v1.2 reasons column and their corresponding data field value. The condition column corresponds to the methodology used by BQ51013B-Q1 to send equivalent message.
