EM LAYOUT

HC05BS8EM USER'S MANUAL
Figure 1-1 shows the layout of the BS8EM. Jumper header P4 controls
the path of a target reset. Jump header P6 lets you select the clock-signal
source. Jumper header P9 allows you to use the on-board emulation
RAM instead of the internal EEPROM of the device during product
development.
Connectors P7 and P8, for a 44-pin QFP or a 52-pin PLCC cable assem-
bly, (purchased separately from the BS8EM.) provide an interface to
your target system. If you install the BS8EM in the MMDS05 station
module, the target cable passes through the slit in the station module
enclosure. Connector P1 connects to 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).
