Probing Capabilities
SX-A devices also provide an internal probing capability
that is accessed with the JTAG pins. The Silicon Explorer II
diagnostic hardware is used to control the TDI, TCK, TMS,
and TDO pins to select the desired nets for debugging.
The user assigns the selected internal nets in Actel Silicon
Explorer II software to the PRA/PRB output pins for
observation. Silicon Explorer II automatically places the
device into JTAG mode. However, probing functionality is
only activated when the TRST pin is driven high or left
floating, allowing the internal pull-up resistor to pull
TRST High. If the TRST pin is held Low, the TAP controller
remains in the Test-Logic-Reset state so no probing can
be performed. However, the user must drive the TRST pin
High or allow the internal pull-up resistor to pull TRST
High.
When selecting the Reserve Probe Pin box as shown in
Figure 1-12 on page 1-9, direct the layout tool to reserve
the PRA and PRB pins as dedicated outputs for probing.
This Reserve option is merely a guideline. If the designer
assigns user I/Os to the PRA and PRB pins and selects the
Reserve
Probe
Pin option, Designer Layout will
override the Reserve Probe Pin option and place the
user I/Os on those pins.
To allow probing capabilities, the security fuse must not
be programmed. Programming the security fuse disables
the JTAG and probe circuitry. Table 1-9 summarizes the
possible device configurations for probing once the
device leaves the Test-Logic-Reset JTAG state.

Notes:
1. If the TRST pin is not reserved, the device behaves according to TRST = High as described in the table.
2. Avoid using the TDI, TCK, TDO, PRA, and PRB pins as input or bidirectional ports. Since these pins are active during probing, input
signals will not pass through these pins and may cause contention.
3. If no user signal is assigned to these pins, they will behave as unused I/Os in this mode. Unused pins are automatically tristated by
the Designer software.
