Figure 19 8-Pin BDM Connector
3.2.2 The M68EVS332
The M68332 EVS is exactly the same as the M68EVK332, but has an additional daughter card called the
M68DICARD. The user communicates with the DICARD, which in turn communicates with the MCU, with a
program called DIBUG (version 1.03 is the latest version). One use for the DICARD is to reprogram the
EPROM on the BCC. See
Application Snapshot
AS-52 for more information (Snapshots are available on-
line — see 6.2 Freeware Data Systems for more information). The M68DICARD is no longer supported or
sold, and neither is the M68EVS332E. The M68EVK332 replaces it.
3.2.3 The M68MEVB1632
The M68MEVB1632 is a more sophisticated development board than the M68332EVK. It consists of a plat-
form board (PFB), a plug-in daughtercard called the personality board (MPB), and the M68ICD32 debugger.
The PFB has memory sockets, logic analyzer connections, and jumpers which allow the user to select the
state of critical boot-up signals such as the data bus pins and MODCLK. The MPB contains the MCU and
crystal. The system is very versatile because there are MPBs for a number of different devices, and several
MPBs can be used with the same PFB. Unlike the M68332EVK, the M68MEVB1632 does not have onboard
EPROM with a monitor. The user must either use pre-programmed ROMs or use the BDM connector to
download code into RAM.
3.2.4 The MMDS1632
The MMDS1632 is an emulator that provides high-speed, real-time hardware and software emulation for
the target system. It replaces the MCU completely. It is designed to work with a package-specific personality
board (PPB) and the MPB. Both of these boards must be purchased separately. The MPB is not necessary
if the user has a target board already built. In this case, a connection from the MMDS1632 can be soldered
or socketed to the connections intended for the MCU. Contact a local Motorola sales office for more infor-
mation on the MMDS1632.
