Interrupt Interface Signals:
These signals comprise the interface used by
external agents to interrupt the R4400 processor
Int(5:1)*
I
Interrupt
: Five of six general processor interrupts, bit-
wise ORed with bits 5:1 of the interrupt register. This
feature available on the R4400PC version only
Int0*
I
Interrupt:
One of six general processor interrupts, bit
wise ORed with bit 0 of the interrupt register
NMI*
I
Nonmaskable interrupt
: Nonmaskable interrupt ORed
with bit 6 of the interrupt register
Initialization Interface:
These signals comprise the interface by which an
external agent initializes the R4400 operating parameters.
ColdReset*
I
Cold Reset:
This signal must be asserted for a power on
reset or a cold reset. The clocks SClock, TClock, and
RClock begin to cycle and are synchronized with the
de-assertion edge of ColdReset*. ColdReset must be de-
asserted synchronously with MasterOut.
ModeClock
O
Boot Mode Clock:
Serial boot-mode data clock output
at the system clock frequency divided by 256
ModeIn
I
Boot mode data in:
Serial boot-mode data input.
Reset*
I
Reset:
This signal must be asserted for any reset
sequence. It may be asserted synchronously or asyn-
chronously for a cold reset, or synchronously to initate
a warm reset. Reset must be de-asserted synchronously
with MasterOut.
VccOk
I
V cc is OK :
When asserted, this signal tells the R4400
that the 3.3 Volt power supply has been above 3.15
Volts for more than 100 milliseconds & will remain sta-
ble . Assertion of VccOK starts initialization sequence.
256K/ 1M*
I
Cache size Select:
Must be connected to ground to
enable the full 1M Byte of cache. Cache size will be
256K if pin is left unconnected.
JTAG Interface Signals
JTDI
I
JTAG data in:
Data is serial, scanned in thru this pin
JTCK
I
JTAG clock input:
The processor outputs a serial clock
on JTCK. On the rising edge of JTCK, both JTDI and
JTMS are sampled.
JTDO
O
JTAG data out:
Data is serial, scanned out thru this pin
JTMS
I
JTAG:
JTAG command signal indicates that the incom-
ming serial data is command clear.
