Not all devices have the AV
device, all must be connected to the appropriate levels in order for the emulator to
operate.
The interconnection is very simple; any problems experienced are often caused by
other connections or components on these critical lines that interfere with the operation
of the MPLAB REAL ICE in-circuit emulator system, as discussed in the next section.
2.5.4
Figure 2-9 shows the active emulator lines with some components that will prevent the
MPLAB REAL ICE in-circuit emulator system from functioning.
FIGURE 2-9:
Specifically, these guidelines must be followed:
• No pull-ups on PGC/PGD – they will divide the voltage levels, since these lines
• No capacitors on PGC/PGD – they will prevent fast transitions on data and clock
• No capacitors on MCLR – they will prevent fast transitions of V
• No diodes on PGC/PGD – they will prevent bidirectional communication between
