[. . . ] The following figure shows the SYSCLKOUT ticks, a sample taken every clock tick, and the Qualification type set to Qualification using 3 samples. In this case, the Qualification sampling period prescaler=0: In the next figure Qualification sampling period prescaler=1. A sample is taken every two clock ticks, and the Qualification type is 7-76 Target Preferences/Custom Board set to Qualification using 3 samples. The output signal changes much later than if Qualification sampling period prescaler=0. In the following figure, Qualification sampling period prescaler=2. Thus , a sample is taken every four clock ticks, and the Qualification type is set to Qualification using 3 samples. 7-77 Target Preferences/Custom Board Flash_loader You can use Flash_loader to: · Automatically program generated code to flash memory on the target when you build the code. · Manually erase, program, or verify specific flash memory sectors. To use this feature, download and install the appropriate TI Flash API plugin from the TI Web site. 7-78 Target Preferences/Custom Board For more information, consult the "Programming Flash Memory"topic in the Target Support Package User's Guide or the *_API_Readme. pdf file included in the TI Flash API downloadable zip file. Enable Flash Programmer Enable the flash programmer by selecting a task for it to perform when you click Execute or build the software. To program the flash memory when you build the software, select Erase, Program, Verify. Detect Flash sectors to erase from COFF file When enabled, the flash programmer erases all of the flash sectors defined by the COFF file. Erase Sector Selection When Detect Flash sectors to erase from COFF file is disabled, the selected flash sectors are erased. Specify API location Specify the directory path of the TI flash API executable you downloaded and installed on your computer. Use Browse to locate the file or enter the path in the text box. Execute Click this button to initiate the task selected in Enable Flash Programmer. 7-79 Target Preferences/Custom Board DMA_ch[#] The Direct Memory Access module transfers data directly between peripherals and memory using a dedicated bus, increasing overall system performance. 7-80 Target Preferences/Custom Board You can individually enable and configure each DMA channel. The DMA module services are event driven. Using the Interrupt source and External pin (GPIO) parameters, you can configure a wide range of peripheral interrupt event triggers. To use DMA with the C280x/C28x3x ADC block, open the ADC block, enable Use DMA (with C28x3x), and select a DMA channel number. To avoid error messages, open the Target Preferences block > Peripherals and disable the same DMA channel number. For more information, consult the TMS320x2833x, 2823x Direct Memory Access (DMA) Module Reference Guide, Literature Number: SPRUFB8A, and the Increasing Data Throughput using the TMS320F2833x DSC DMA training presentation (requires login), both available from the TI Web site. Enable DMA channel Enable this parameter to edit the configuration of a specific DMA channel. If your model includes an C280x/C28x3x ADC block with the Use DMA (with C28x3x) parameter enabled, disable the same DMA channel here in the Target preferences block. This parameter has no corresponding bit or register. Data size Select the size of the data bit transfer: 16 bit or 32 bit. [. . . ] Selecting this parameter enables Export IDE link handle to base workspace and makes it non-editable, since Embedded IDE Link must create a handle. Setting Build action to Archive_library or Create_processor_in_the_loop project removes this parameter.
