Note
When you modify/display internal RAM or SFR, the emulator breaks
into the monitor, and the monitor program reads the contents of
memory. This is because the emulator uses internal RAM and SFR of
emulation processor to perform emulation. Note that user program
execution is suspended to modify/diplay internal RAM or SFR.
Note
You can configure the emulator so that data write cycles are performed
to both internal RAM (or SFR) and emulation memory. In this case,
you can display the data written to emulation memory without
suspending user program execution. Refer to chapter 4 of this manual
for more details.
Stepping Through
the Program
You can also direct the emulator processor to execute one instruction or
number of instructions. Type:
M> s 1 0c000;reg
This command steps 1 instruction from address 0c000 hex, and
displays registers. You will see:
000c000 - LDX #027fH
PC = 000c003
reg pg=00 pc=c003 ps=0021 dt=00 sp=027f a=ff00 b=0000 x=027f y=0021 dpr=0000
To step one instruction from present PC, you only need to type s at
prompt. Type:
M> s;reg
