Test and JTAG Signals
JTAG is the IEEE 1149.1 test access port. The JTAG input signals have a weak pullup resistor
internal to the chip, so that any input that is not terminated, is interpreted as a high. Other test
signals are network processor specific, for manufacturing use only. See Table 15.
PAS1_VCCA
1
DLL power. Should be generated by filtering VCC with an LC network
PAS2_VCCA
1
DLL power. Should be generated by filtering VCC with an LC network
PAS3_VCCA
1
DLL power. Should be generated by filtering VCC with an LC network
VREF_QDR0
2
QDR reference voltage.
VREF_QDR1
2
QDR reference voltage.
VREF_QDR2
2
QDR reference voltage.

Description
Number
JTAG_TCK
I
Test interface reference clock that times all the transfers on
the JTAG test interface.
1
JTAG_TMS
I
Test interface mode select. Tms causes state transitions in
the test access port (TAP) controller.
1
JTAG_TDI
I
Test interface data input. Tdi is the serial input through
which JTAG instructions and test data enter the JTAG
interface.
1
JTAG_TDO
OZ
Test interface data output. Tdo is the serial output through
which test instructions and data from the test logic leave
the network processor.
