5.10.5 Null requests
Figure 10-4 illustrates the SysCmd format for null requests.

Figure 10-4 Bit Definition of the SysCmd Bus for Null Requests
Null request commands are always used for system interface release external null requests. Table 10-8
indicates methods of specifying SysCmd(4:3) for system interface release external null requests.
SysCmd(2:0) is reserved for null requests.

5.10.6 Syntax of system interface data identifiers
This section defines methods of specifying the SysCmd bus for system interface identifiers. The bit
structure illustrated in Figure 10-5 is common to all system interface data identifiers.
Figure 10-5 Bit Definition of SysCmd Bus for Data Identifiers
SysCmd(8) must always be set to “1” for system interface data identifiers. System interface data
identifiers are in the non-coherent data format.
5.10.7
Non-coherent data
Non-coherent data are data such as the following.
Data that are the subject of a processor block write request or a processor double word/partial
double word/word/partial word write request.
Data that are returned to a processor non-coherent block read request or a processor double word/
partial double word/word/partial word read request.
Data that are the subject of an external write request.
Data that are returned to an external read request as a response.
