Appendix 10  System Memory List  
System memory is used for exchanging information between the host and the PT, such as 
controlling the PT and notifying the host of PT status. 
The system memory is divided into bit and word sections. 
 
System Bit Memory ($SB)   
System bit memory ($SB) is used for exchanging information between the host and the PT 
in bit units, such as controlling the PT and notifying the host of PT status. 
The system bit memory contains 64 bits with predefined functions. 
The system bit memory is listed in the following table.
