Table 5 System Interface
Pin Name
Type
Description
ExtRqst*
Input
External Request
Signals that the system interface is submitting an external request.
Release*
Output
Release Interface
Signals that the processor is releasing the system interface to slave
state.
RdRdy*
Input
Read Ready
Signals that an external agent can now accept a processor read.
WrRdy*
Input
Write Ready
Signals that an external agent can now accept a processor write
request.
ValidIn*
Input
Valid Input
Signals that an external agent is now driving a valid address or data on
the SysAD bus and a valid command or data identifier on the SysCmd
bus.
ValidOut*
Output
Valid Output
Signals that the processor is now driving a valid address or data on the
SysAD bus and a valid command or data identifier on the SysCmd bus.
SysAD[63:0]
Input/Output
System Address/Data bus
A 64-bit address and data bus for communication between the
processor and an external agent.
SysADC[7:0]
Input/Output
System Address/Data check bus
An 8-bit bus containing parity check bits for the SysAD bus during data
cycles.
SysCmd[8:0]
Input/Output
System Command/Data identifier bus
A 9-bit bus for command and data identifier transmission between the
processor and an external agent.
SysCmdP
Input/Output
Reserved for system Command/Data identifier bus parity
For the RM5261A, unused on input and zero on output.
