Hardware Description and Board Operation
3-18 M68VZ328ADS USER’S MANUAL MOTOROLA
3.2 CONTROL SWITCHES
There are two push buttons on the ADS which function as follows:
1. Reset Switch (SW2): When pressed, a hardware reset is generated to the
MC68VZ328 processor and resumes operation.
2. Abort Switch (SW1): This switch is used to generate a level 7 interrupt to the
MC68VZ328 processor for aborting normal software execution and returning control
to the debug monitor.
3.3 DIP SWITCHES
There are two DIP switch packs on the ADS board, S1 and S2. S1 is used to configure the
memory system and operation modes. S2 is used to enable the on-board peripheral such
as buzzer and touch panel controller. Table 3-1 and Table 3-2 show the description of each
switch.
* Used as monitor and debug port selection in provided monitor program
3.4 OPERATION MODES
M68VZ328ADS supports two operation modes of MC68VZ328: Normal Mode and Boot-
strap Mode. Selection of those operation modes is controlled by setting DIP switch S2-8.
Operation mode has to be selected before resetting the system. Mode is not allowed to be
changed during normal runing. Table 3-3 shows the operation mode configuration.
Normal mode - After power up or system reset in this mode, CSA0 is default to cover the
whole memory map except MC68VZ328 internal registers and EMU space. Also, as reset

ROM in which the first two words are reset vectors. The default boot ROM of the
M68VZ328ADS has been programmed with monitor when it is shipped out from factory. Pls.
refer to Quick Installation part for detailed description on the selection of monitor and debug
port.
Bootstrap mode - When this mode is selected, the DragonBall-VZ will start its embedded
bootloader. User can use this mode to do simple debugging or reprogram the flash memo-
ries. For detailed bootstrap mode operation, please refer MC68VZ328 user’s manual.
3.5 LED INDICATORS
There are four LED indicators on the ADS which function as shown in Table 3-4.
The LED3 is connected to a counter. The counter is toggled by address line A1.
3.6 MEMORY
M68VZ328ADS provides on-board Flash memory and SDRAM, for application develop-
ment. They can be enabled or disabled individually by setting the corresponding DIP
switches.
3.6.1 Memory Map
The default memory map of M68VZ328ADS in normal mode is shown in Table 3-5. The chip
select range to all of the memory are software programmable. Users can reconfigure the
memory map for their applications.

Hardware Description and Board Operation

3.6.2 FLASH Memory
M68VZ328ADS is equipped with two 2M-byte Flash memory chips. Figure 3-2. shows the
interface of them. They are chip-selected by *CSA0 and *CSA1 signals. The connection of
these *CSAx signals to the Flash memories is controlled by DIP switches S2-1, S2-2 and
S2-3.
When S2-1 and S2-3 are close, *CSA0 connects Flash0 and *CSA1 connects Flash1.
Flash0 becomes the boot ROM. When S2-1 and S2-3 are open and S2-2 is close, *CSA0
connects Flash1 only. Flash1 will then be boot ROM instead. So, user can select either
FLASH0 or FLASH1 to be the boot ROM. These configuration allow users to put their appli-
cation program to boot ROM without having to erase the on-board monitor program.
Table 3-6 summaries the possible configuration of the S2-1, S2-2 and S2-3.
For more details on flash memory programming, please refer to Appendix B .
