1.2 EM LAYOUT
Figure 1-1 shows the layout of the E24EM. Jumper header J1 selects factory test or user
mode. J2 controls the path of a target reset. J3 and J4 allow the clock source to be selected. J5
selects between MMDS05 and EVS operation.
Connector P1 is for a logic analyzer. (Connector P1 has more significance for an EVS system,
as an MMDS05 system includes a bus analyzer.) Expansion header connectors P2 and P3
connect together the EM and the control board (for an MMDS05) or the EM and the platform
board (for an EVS). Finally, Connectors P4 and P5 allow for connection of a target cable
which is available separately. If you install the E24EM board in the MMDS05, the target cable
passes through a slit in the MMDS05 enclosure.
