DESCRIPTION
TEST SIGNALS (CONTINUED)
EMU1 / OFF 77
I/O/Z
Emulator pin 1. Emulator pin 1 disables all outputs. When TRST is driven high, EMU1 / OFF is used as an
interrupt to or from the emulator system and is defined as an input / output through the JTAG scan. When TRST
is driven low, this pin is configured as OFF. EMU1 / OFF, when active low, puts all output drivers in 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 = 0
EMU0 = 1
EMU1 / OFF = 0
