RC64474 RC64475
Pin Desc ription Table
The following is a list of systeminterface pins available on the RC64474/475. Pin names ending with an asterisk (* are active when low
Pin Name
Type
Desc ription
SystemInterface
ExtRqst*
I
External request
An external agent asserts ExtRqst*to request use of the Systeminterface. The processor grants the request by asserting
Release*
Release*
O
Release interface
In response to the assertion of ExtRqst*or a CPU read request, the processor asserts Release*and signals to the request-
ing device that the systeminterface is available.
RdRdy*
I
Read Ready
The external agent asserts RdRdy*to indicate that it can accept a processor read request.
WrRdy*
I
Write Ready
An external agent asserts WrRdy*when it can now accept a processor write request.
ValidIn*
I
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 iden-
tifier on the SysCmd bus.
ValidOut*
O
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)
I/O
System address/data bus
A 64-bit address and data bus for communication between the processor and an external agent. During address phases
only, SysAd(35:0) contains valid address information. The remaining SysAD(63:36) pins are not used. The whole 64-bit
SysAD(63:0) may be used during the data transfer phase.
In 32-bit mode and in the RC64474, SysAD(63:32) is not used, regardless of Endianness. A 32-bit address and data com-
munication between processor and external agent is performed via SysAD(31:0).
SysADC(7:0)
I/O
System address/data check bus
An 8-bit bus containing parity check bits for the SysAD bus during data bus cycles.
In 32-bit mode and in the RC64474, SysADC(7:4) is not used. The SysADC(3:0) contains check bits for SysAD(31:0).
SysCmd(8:0)
I/O
System command/data identifier bus
A 9-bit bus for command and data identifier transmssion between the processor and an external agent.
SysCmdP
I/O
SystemCommand Parity
A single, even-parity bit for the Syscmd bus. This signal is always driven low.
Clock/Control Interface
MasterClock
I
Master Clock
Master clock input establishes the processor and bus operating frequency. It is multiplied internally by 2,3,4,5,6,7,8 to gen-
erate the pipeline clock (PClock). This clock must be driven by 3.3V (Vcc) clock signals, regardless of the 5V tolerant pin
setting.
V
CC
P
I
Quiet VCC for PLL
Quiet V
CC
for the internal phase locked loop.
V
SS
P
I
Quiet V
SS
for PLL
Quiet V
SS
for the internal phase locked loop.
Interrupt Interface
Int*5:0)
I
Interrupt
Six general processor interrupts, bit-wise ORed with bits 5:0 of the interrupt register.
