EMU1/OFF
I/O/Z
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 I/O
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
