DESCRIPTION

NAME

Emulator 0 pin. When TRST is driven low, EMU0 must be high for activation of the OFF condition. When TRST

EMU0(7)

I/O/Z

is driven high, EMU0 is used as an interrupt to or from the emulator system and is defined as input/output by

way of the IEEE standard 1149.1 scan system.

Emulator 1 pin/disable all outputs. When TRST is driven high, EMU1/OFF is used as an interrupt to or from the

emulator system and is defined as input/output by way of IEEE standard 1149.1 scan system. When TRST is

driven low, EMU1/OFF is configured as OFF. The EMU1/OFF signal, when active low, puts all output drivers into

the high-impedance state. Note that OFF is used exclusively for testing and emulation purposes (not for

EMU1/OFF(7)

I/O/Z

multiprocessing applications). Therefore, for the OFF condition, the following apply:

TRST = low,

EMU0 = high

EMU1/OFF = low

(7)

This pin must be pulled up with a 4.7-k

Ω resistor to ensure the device is operable in functional mode or emulation mode.
