Wait command indicate that the instruction of the card reader to be received such as smart card, Process indicate that smart card is in data handling procedure
In, Constant mode expressions require load blocks to be in constant power dissipation pattern, and Variable mode indicate that load blocks can
Exit constant power dissipation pattern.
From fig. 6 it can be seen that when the intelligent card chip 5 receives or waits the instruction of card reader to be received, it is described negative
Module is carried to need to be in constant power dissipation pattern；When the intelligent card chip 5 receives and executes instruction, such as process a2, b2, b5,
The constant power dissipation state that the load blocks can be released temporarily does not influence contactless communication interaction；In the intelligent card chip 5
When sending out response data, the load blocks are also required to be in constant power dissipation pattern；If it is longer to execute instruction the time, according to ISO/
14443 agreements of IEC, smart card need to apply for the additional stand-by period, interactive process b3, b4 at this moment, the load blocks
It needs to be in constant power dissipation pattern.
Into and exit there are many specific implementations of constant power dissipation pattern, the present embodiment provides the following two kinds.
Mode one, the intelligent card chip 5 can exit finger when carrying out data processing to the transmission of the controller 308
It enables, the controller 308 can exit constant power dissipation pattern according to the exit instruction；The intelligent card chip 5 is passing through
When the coil 1 carries out data interaction, it can be transmitted into instruction to the controller 308, so that 308 basis of the controller
The entry instruction enters constant power dissipation pattern.
Mode two, the controller 308 can obtain the status information of the transmission of the intelligent card chip 5；If the state
Information indicates that the intelligent card chip 5 is in the state for carrying out data processing, then exits constant power dissipation pattern；If the state letter
Breath indicates that the intelligent card chip 5 is in the state that data interaction is carried out by the coil 1, then enters constant power dissipation pattern.
Wherein, the status information can be indicated by low and high level or analog voltage, such as 00 indicates to carry out data
