DGCMD 

         Device Generic Command Register
  
  This register enables software to program the controller using a single generic command interface to send link management packets and notifications. This register contains command, control, and status fields relevant to the current generic command, while the DGCMDPAR register provides the command parameter.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

8 CMDIOC 
Command Interrupt on Complete
  
  When this bit is set, the device controller issues a Generic Command Completion event after executing the command. 
  
  Note that this interrupt is mapped to DCFG.IntrNum.
  
  Note: This field must not set to '1' if the DCTL.RunStop field is '0'.
