DESCRIPTION

JTAG INTERFACE*

JTAG Test/EmbeddedICE™ clock input signal. Must be pulled-up for

I

normal operation (56 kΩ is recommended for compatibility with ARM’s

EmbeddedICE)

JTAG Test/EmbeddedICE mode select input signal. Must be pulled-up

I

for normal operation (56 kΩ is recommended for compatibility with

ARM’s EmbeddedICE)

JTAG Test/EmbeddedICE data input signal. Must be pulled-up for

I

normal operation (56 kΩ is recommended for compatibility with ARM’s

EmbeddedICE)

O

JTAG Test/EmbeddedICE data output signal.

RESERVED INTERFACE

I

Reserved. Must be tied HIGH for normal operation.

POWER SIGNALS

I

Power. All LH77790B are 5 V/3.3 V.

I

Ground. All ground pins must be used.

NO CONNECT

—

No connection.

NOTE: *JTAG Reset, TRST, is internally connected to RESETI. IEEE 1149.1 – 1990 Standard requires JTAG Inputs to be pulled

up to a good logic level to achieve normal operations.
