2.5.2
Using the high-speed driver/receiver board combination, the MPLAB REAL ICE
in-circuit emulator is connected to the target device with an 8-pin interface. The pin
numbering for the connector is shown from the top of the target PC board in Figure 2-7.
FIGURE 2-7:
2.5.3
Figure 2-8 shows the interconnections of the MPLAB REAL ICE in-circuit emulator to
the connector on the target board. The diagram also shows the wiring from the
connector to a device on the target PC board. A pull-up resistor (usually around 10 kΩ)
is recommended to be connected from the V
be strobed low to reset the device.
FIGURE 2-8:
In the following descriptions, only three lines are active and relevant to core emulator
operation: pins 1 (V
shown on the above diagram for completeness, but are only sensed, not provided or
controlled, by the emulator.
Be aware that the target V
target low-voltage operation. If the emulator does not sense voltage on its V
2 of the interface connector), it will not operate.

Connections at the emulator and target are mirror images of each other,
i.e., pin 1 on the receiver board is connected to pin 1 on the target board.
