SYStem.MemAccess Memory access selection

Selects the method for realtime memory access while the core is running.

All debugger windows which are opened with the option /E will use the selected non intrusive memory

access.

Format: SYStem.MemAccess <mode>

<mode>: QUiCK

NBD

Denied

QUICK Does a pseudo realtime access. For each single memory access the application is

interrupted for about 50 CPU clocks (10 MHz --> 5 us interruption). This method

can only be used if NO breakpoints are set. The JTAG clock speed should be as

fast as possible to get good performance.

NBD Requires extra debugger hardware to handle the CPUs NBD-interface. This

interface allows a non intrusive memory access while the core is running.

Denied Disables any realtime memory access.
