SYStem.Option TraceStrobe Obsolete command
This command is obsolete.
SYStem.Option TRST Allow debugger to drive TRST
Default: ON.
If this option is disabled the nTRST line is never asserted by the debugger (permanent high). Instead five
consecutive TCK pulses with TMS high are asserted to reset the TAP controller which have the same effect.
SYStem.Option TURBO Speed up memory access
Default: OFF.
If TURBO is disabled the CPU checks after each system speed memory access in debug mode if the CPU
has finished the corresponding cycle. This check will significantly reduce the down- and upload speed (30-
40%).
If TURBO is enabled the CPU will make no checks. This may result in unpredictable errors if the memory
interface is slow. Therefore it is recommended to use this option only for a program download and in case
you know that the memory interface is fast enough to take the data with the speed they are provided by the
debugger.
This option is not available on the ARM10.
