Content of the pause register is a data address associated with a command data. In addition, the pause register includes a pause code. When the pause code is equal to a first value, after the multimedia chip reads command data associated with the content of the pause register, reading is stopped, and the command data next to the command data are to be read in the next reading. When the pause code is equal to a second value, after the multimedia chip reads the command data associated with the content of the pause register, the multimedia chip continues to reads command data associated with the beginning register.
