Absolute Maximum Ratings
Note: Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
VCCPI
Quiet VCC for PLL
Quiet VCC for the internal phase locked loop.
VSSPI
Quiet VSS for PLL
Quiet VSS 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.
NMI*
I
Non-maskable interrupt
Non-maskable interrupt, ORed with bit 6 of the interrupt register.
Initialization Interface
VCCOkI
VCC is OK
When asserted, this signal indicates to the R4700 that the power supply has been above the Vcc minimum
for more than 100 milliseconds and will remain stable. The assertion of VCCOk initiates the reading of the
boot-time-mode-control serial stream.
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.
Reset*
I
Reset
This signal must be asserted for any reset sequence. It may be asserted synchronously or asynchronously
for a cold reset, or synchronously to initiate a warm reset. Reset 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 two hundred fifty-six.
ModeIn
I
Boot-mode data in
Serial boot-mode data input.
