2. Load the address of the first instruction to be executed into the program counter.
The debugger should now work reliably. That is, programs can be downloaded into the RAM and exe-
cuted. Alternatively, write the reset vector to memory location $000000 and then reset the MCU. The
reset vector is discussed in detail in 4.1.3.1 Initializing the Reset Vector.
3.2 Communicating with Freescale Boards
Third party vendors sell many types of development tools to help establish communication with the
MCU. These tools are described in the Freescale
Microcontroller Development Tools Directory. Howev-
er, this tutorial focuses only on Freescale evaluation boards.
3.2.1 The M68HC16Z1EVB
The M68HC16Z1EVB is an evaluation board that consists of a platform board with the processor held
in place by a socket. The board has logic analyzer connectors and sockets for external memory. It also
has a built-in background debug mode (BDM) connector for use with a debugger. The necessary logic
is already on the board, so the user can use a standard 25-pin connector cable and does not need an
ICD16 cable with the 10-pin connector.
To run the board as a stand-alone system and not use BDM, simply remove the PAL (U5) that is sock-
eted onto the EVB. Then change jumpers J1 and J4 from the pseudo-ROM position to the EPROM po-
sition. On some older boards, the PAL may be soldered to the EVB. In this case, configure the PAL so
that its inputs appear as if they are connected to the PC. Connect the following pins to ground and +5
volts as shown:
ground:
DB25 pins 6, 8, 21
PAL pins 6, 10, 11
+5 volts:
DB25 pins 4, 7, 13
PAL pins 4, 9, 20
3.2.2 The M68MEVB1632
The M68MEVB1632 is a newer and more sophisticated development board than the M68HC16Z1EVB.
It consists of a platform board (PFB), a plug-in daughtercard called the personality board (MPB), and
the M68ICD16 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 MOD-
CLK. 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.
3.2.3 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
Freescale sales office for more information on the MMDS1632.
