5 The SX-Key Debugger
5.1.2
The Debug window contains buttons for debugging functions. Each button has an associated shortcut
key, as described in Table 2 – Debugger Buttons and Shortcut Keys, below.

The Step button (or Alt-S) will execute one machine instruction and update all registers.
The Walk button (or Alt-W) will execute one machine instruction after another in “slow motion”,
updating the display automatically and continuing until the Stop button is pressed, or a breakpoint
is encountered. The delay time between instruction executions can be selected from the Update Speed
drop-down list; with the range being from 1 (about one second) to Max (as fast as the computer can
process it).
The Run button (or Alt-R) will initiate a full-speed execution of the program, and will continue until
a breakpoint is hit or the Stop or Reset buttons are pressed. The displayed registers will not update
until the Poll button is pressed or execution is stopped.
The Poll button (or Alt-L) operates in one of two modes. If a breakpoint exists, the Poll button runs
the code at full speed halting execution at the break just long enough to update the display and then
continues running. If a breakpoint is not set, the Poll button can be pressed only during run mode to
get an instant update of the register displays.
The Stop button (or Alt-P) halts execution of a walk, run or poll operation and updates the display.
The Reset button (or Alt-T) returns the SX chip to its initial state and sets the program counter (PC)
to the location containing the reset vector.
The Registers, Code and Watch buttons (or Alt-E, Alt-D, Alt-C) bring the associated windows into
view if they were hidden. (The Debug window always stays on top).
The Reset Pos. button brings all windows into view, places them at their default positions, and
resizes them to the defaults.
The Quit button (or Alt-Q) closes the Debug windows and exits debug mode.
