8.5.3Dual Interrupt Driven Mode
The following descriptions explain the software for the data acquisition in Dual Interrupt Driven Mode (using the CSTART signal). The required interface connections are shown in Figure 2.
Program Files:
DUALIRQ1.ASM | Includes the complete software algorithm to control the Dual IRQ Driven Mode |
CALIBRAT.ASM | Calibration procedure of the DAC |
CONSTANT.ASM | Common file of all modes (constants definition) |
VECTORS.ASM | Common file of all modes (IRQ vector table) |
Other Files: |

linker.cmd | Organization of the DSP memory (data and program memory) |
auto.bat | Batch file to start the compiler for the dual interrupt driven software |
asm500.exe | 54x Code compiler |
lnk500.exe | C54x linker |
The timing requirements to interface the ’C54x to the ADC are provided in Table 9. The STEP numbers given there can be found again as Marker in the code. This helps to debug and verify the code.
