5.3.1 Interface bus
Figure 5.3-1 illustrates the 64-bit address/data bus SysAD (63:0), which is the main communication bus of
the system interface, and the 9-bit command bus SysCmd (8:0). SysAD and SysCmd are bi-directional
busses. In other words, these two busses are used for the processor to issue processor requests and for the
external agent to issue external requests.

Requests sent via the system interface consist of the following:
Address
System interface command that strictly specifies the type of request
Series of data elements for when the request is a particular write or read process.
5.3.2 Address cycle and data cycle
Cycles during which valid addresses exist on the SysAD bus are referred to as address cycles. Also,
cycles during which valid data exist on the SysAD bus are referred to as data cycles. Validity is
determined depending on the ValidIn* signals and ValidOut* signals.
The SysCmd bus is used to identify the contents of the SysAD bus for all cycles at which it is to be valid.
The most significant bit of the SysCmd bus is used to indicate whether the current cycle is an address
cycle or a data cycle.
In the case of an address cycle [SysCmd(8) = 0], the remaining bits SysAD(7:0) of the SysCmd
bus contain the system interface commands.
In the case of a data cycle [SysCmd(8) = 1], the remaining bits SysAD(7:0) of the SysCmd bus
contain the data identifier.
