RTDX manager properties - help extract

The following target configuration properties can be set for the RTDX module in the RTDX Manager Properties dialog of the Configuration Tool or in a DSP/BIOS TextConf script:

Enable Real-Time Data Exchange (RTDX). This box should be checked if you want to link RTDX support into your application.

TextConf Name: ENABLERTDX Type: Bool

Example: RTDX.ENABLERTDX = true;

RTDX Mode. Select the port configuration mode RTDX should use to establish communication between the host and target. The default is JTAG for most targets. Set this to simulator if you use a simulator. The HS-RTDX emulation technology is also available. If this property is set incorrectly, a message says "RTDX target application does not match emulation protocol" when you load the program.

TextConf Name: MODE Type: EnumString

Options: "JTAG", "HSRTDX", "Simulator"

Example: RTDX.MODE = "JTAG";

RTDX Data Segment (.rtdx_data). The memory segment used for buffering target-to-host data transfers. The RTDX message buffer and state variables are placed in this segment.

TextConf Name: RTDXDATASEG Type: Reference

Example: RTDX.RTDXDATASEG = prog.get("myMEM");

RTDX Buffer Size (MADUs). The size of the RTDX target-to-host message buffer, in minimum addressable data units (MADUs). The default size is 1032 to accommodate a 1024-byte block and two control words. HST channels using RTDX are limited by this value.

TextConf Name: BUFSIZE Type: Int16

Example: RTDX.BUFSIZE = 258;

RTDX Interrupt Mask. This mask interrupts to be temporarily disabled inside critical RTDX sections. The default value of zero (0) disables all interrupts within critical RTDX sections. Such sections are short (usually <100 cycles). Disabling interrupts also temporarily disables other RTDX clients and prevents other RTDX function calls.

You should allow all interrupts to be disabled inside critical RTDX sections if your application makes any RTDX calls from SWI or TSK threads. If your application does not make RTDX calls from SWI or TSK threads, you may modify bits in this mask to enable specific high-priority interrupts. See the RTDX documentation for details.

TextConf Name: INTERRUPTMASK Type: Int16

Example: RTDX.INTERRUPTMASK = 0x00000000;
