2.1 Designing Your Target System’s MPSD Emulator Connector (12-pin Header)
The ‘C3x devices support complete emulation through a dedicated serial scan path
port. This port uses a modular port scan technology (MPSD). For the application target
system to communicate with the EMU320C3x your target system must have a 12-pin
header(2x6). The pin signal assignments are shown in figure 2-1. Pin 8 is removed for
keying purposes.
Figure 2-1. 12-Pin Header Signals and Header Dimensions
Note: Signals EMU0, EMU1, EMU2 should always be pulled up with a separate 20k
ohm resistors to Vcc.
Position pin 8 will be plugged to prevent improper connection. Pin 8 is present
in the cable and is grounded.
