TEST SIGNALS (CONTINUED)
TRST
30
I
JTAG test reset with internal pulldown. TRST, when driven high, gives
the scan system control of the operations of the device. If this signal is
not connected or driven low, the device operates in its functional mode,
and the test reset signals are ignored.

EMU0
45
I/O
I
Emulator I/O pin 0 with internal pullup. When TRST is driven high, this
pin is used as an interrupt to or from the emulator system and is defined
as input/output through the JTAG scan.

EMU1/OFF
47
I/O
I
Emulator I/O pin 1 with internal pullup. When TRST is driven high, this
pin is used as an interrupt to or from the emulator system and is defined
as input/output through JTAG scan.

I = input, O = output, Z = high impedance
The reset state indicates the state of the pin at reset. If the pin is an input, indicated by an I, its state is determined by user design. If the pin is
an output, its level at reset is indicated.
§ At reset, the device comes up with AVIS mode enabled. The data bus is in output mode while AVIS is enabled.
NOTE: Bold, italicized pin names indicate pin function after reset.
