Mictor Connector (J12)
The Mictor connector (J12) can be used to transmit up to 27 high-speed
I/O signals with very low noise via a shielded Mictor cable. J12 is used as
a hardware or software debug port.
Table 2–27 lists the Mictor connector references.
The Mictor connector signals are allocated as follows:
■ Twenty-five data signals
■ One clock input signal
■ One clock output signal
Pin allocation is shown in Figure 2–19 on page 2–54 and listed in
Table 2–28 . Most of the pins on J12 connect to the I/O pins on the EP2C70.
For systems that do not use the Mictor connector for debugging the
Nios II processor, any on-chip signals can be routed to I/O pins and
probed at the Mictor connector (J12) via a Mictor cable.
You can also connect external scopes and logic analyzers to J12 to analyze
large number of signals simultaneously.

The JTAG signals have special usage requirements. You cannot
use J12 and J9 at the same time.
