DESCRIPTION
Emulator 0 pin. When TRST is driven low, EMU0 must be high for activation of the OFF condition. When TRST
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
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-kΩ resistor to ensure the device is operable in functional mode or emulation mode.
