==== 4.6.1 MANAGE CHANNEL CLOSE Command ====

Upon receiving a MANAGE CHANNEL CLOSE command on an I/O interface, the Java Card RE shall run the following procedure: 

1. The MANAGE CHANNEL CLOSE command uses: CLA=**%b000000cc*** (where **cc** in the bits (b2,b1) denotes the origin logical channel: 0-3) or CLA=**%0100dddd*** (where **dddd** in the bits (b4-b1) denote the origin logical channel:** **4-19), INS=**0x70**, P1=**0x80** and P2 specifies the logical channel to be closed. 

 

  *If the MANAGE CHANNEL CLOSE command has non-zero secure messaging bits (b4,b3) in the CLA byte when the origin logical channel is 0-3 or non-zero bit (b6*) when the origin logical channel is 4-19, the Java Card RE responds with status code **0x6882** (**SW_SECURE_MESSAGING_NOT_SUPPORTED**).    

  *If the MANAGE CHANNEL command is issued with P1 not equal **0** or **0x80**, the Java Card RE responds with status code **0x6A81** (**SW_FUNC_NOT_SUPPORTED**).    

2.  If the origin logical channel on the I/O interface that received the MANAGE CHANNEL CLOSE command is not open, the Java Card RE responds with status code **0x6881** (**SW_LOGICAL_CHANNEL_NOT_SUPPORTED**). 

3.  If the Java Card RE supports only the basic logical channel on the I/O interface that received the MANAGE CHANNEL CLOSE command, the Java Card RE responds with status code **0x6881** (**SW_LOGICAL_CHANNEL_NOT_SUPPORTED**). 

4.  If the specified logical channel to close is the basic logical channel (logical channel **0**) or the specified logical channel number is greater than 19, the Java Card RE responds with status code **0x6A81** (**SW_FUNC_NOT_SUPPORTED**). 

5.  If the specified logical channel to close is currently open on the I/O interface that received the MANAGE CHANNEL CLOSE command, deselect the active applet instance (if any) on the specified logical channel as described above in [[4.6_Applet Deselection| Section 4.6, Applet Deselection]]. The specified logical channel is now closed. The Java Card RE responds with status code **0x9000**. 

6.  Otherwise, if the specified logical channel is closed or not available on that I/O interface, the Java Card RE responds with warning status code **0x6200** (**SW_WARNING_STATE_UNCHANGED**).
