User Code
Generation
EVB user code can be generated by two methods:
1.
For small programs or subroutines, D-Bug12’s single-line
assembler/disassembler may be used to place object code directly into
the EVB’s memory.
2.
For larger programs, the IASM12 assembler may be used on a host
computertogenerateS-recordobjectfiles,whichthencanbeloadedinto
the EVB’s memory using D-Bug12’s FLOAD or LOAD command.
If the M68HC912B32’s BDM interface serves as the user interface, the SCI
(serial communication interface) port becomes available for user applications.
This mode requires a background debug development tool, such as Motorola’s
SDI
interface, and a host computer with the appropriate interface software or
another B32EVB.
At reset, the EVB can begin operation in either of four jumper-selectable
modes:
1.
In EVB mode, D-Bug12 immediately issues its command prompt on the
terminal display and waits for a user entry.
2.
In the jump-to-EEPROM mode, execution begins directly with the user
code in on-chip EEPROM.
3.
InBDMpodmode,D-Bug12servesasaprobeinterfacebetweenatarget
system and the user via the BDM out connector.
4.
In bootload mode, a user program may be loaded into the host EVB’s
byte-erasable or FLASH EEPROM memory.
