Bus Interface Descriptions
PLLTSTp
Test Enable
This signal is strapped LOW, which means that testing is
generally disabled.
Input to PLL Circuit
PLLVDD
PLL Power
This signal provides VDD power.
Input to PLL Circuit
PLLVSS
PLL Ground
This is the ground for the PLL circuit.
Ground
5.1.4 Test Signals
There are nine pins on the LR4500 chip that allow designers at LSI Logic
to test the device using an LSI Logic tester. When the pins are not being
used for testing, you must deassert all inputs by strapping active-high
signals LOW and active-low signals HIGH. You must leave all outputs
unconnected. Inputs are referenced to and outputs are referenced from
the LR4500.
ICECLKp
ICE Serial Bit Clock Rate X16
The ICEport requires an off-chip pin with a clock that runs
at 16 times the serial transmit/receive rate.
Input
ICERXp
RX Serial Bit Receive
This signal carries the ICEport UART (universal
asynchronous receiver/transmitter) serial input data
stream.
Input
ICETXP
TX Serial Bit Transmit
This output sends out the ICEport UART serial data
stream.
Output
PARAMOUTp Parametric NAND Tree—LSI Logic Use Only
This output is used to check the parametric NAND tree.
It is reserved for factory use during testing. Leave it
unconnected on the board.
Output
SCANCRip
CW4011 Core Scan—LSI Logic Use Only
Strap this signal LOW on the board.
Input
SCANCRop
CW4011 Core Scan—LSI Logic Use Only
Leave this signal unconnected.
