 address range, file number (FN), channel number (CN), 
 submode (SM), and coding information (CI). 
 The mask pattern 
 can be specified for the submode (SM) and coding information (CI), and 
 ({SM | CI} & mask pattern == comparison pattern) 
 Read the sector. 

 Stream group 

 A collection of multiple streams. 

 final stream 

 The stream that is regenerated last in the stream group. 

 Loop start stream

 destination stream after playing the last stream of the stream group. 

 Number of loops

 pickup is moved to the loop start stream after playing the final stream. 

 Transfer start FAD 

 Pickup that starts transferring data read into the CD buffer to a buffer in the program Position of. 

 Transfer gate
