Without a stack pointer, the emulator is unable to make the transition to

the run state, step, or perform many other emulation functions.
However, using this option does not preclude you from changing the
stack pointer value or location within your program; it just sets the
initial conditions to allow a run to begin.
cf tdma
The tdma (trace internal DMA cycles) configuration item defines
whether or not the emulator traces internal DMA cycles.
When you enable this item with the above command, each time DMA
performed, one emulation analyzer state will be generated to recognize
the DMA cycle.
When disabled, no analyzer state will be generated at the occurrence of
DMA. Therefore, any DMA cycle will be ignored by the analyzer.
Internal DMA cycles may be traced regardless of this configuration in
Note
order to disassemble the trace list correctly.
cf trfsh
The trfsh (trace refresh cycles) configuration item defines whether or
not the emulator traces refresh cycles.
When you enable this item with the above command, refresh cycles are
traced by the emulation analyzer.
When disabled, refresh cycles are not traced by the analyzer.
