Single Step (Trace)
The STEP command executes a specified hexadecimal number of
instructions, beginning at the current program counter (PC) address
value. If a number is not specified, this command executes one
instruction. The STEP, ST, and T commands are identical.
Syntax:
STEP [< count >]
Where:
< count > The hexadecimal number of instructions to be
executed. Hexadecimal $7FF is the maximum
value.
Do not use any step command (ST, STEP, STEPFOR, STEPTIL, or T)
if the PC points to internal RAM or EEPROM or if the code branches into
internal RAM or EEPROM.
The step commands are not real-time. They execute one instruction at a
time, then return control to the monitor. Do not rely on timer values.
Examples:
>STEP Execute the instruction at the current PC address
value.
>STEP 2 Execute two instructions, starting at the current PC
address value.
