CHAPTER 8: DEBUGGER
182 EPSON S5U1C63000A MANUAL
(S1C63 FAMILY ASSEMBLER PACKAGE)
n (next)
Function
This command single-steps the target program from the current PC position by executing one instruc-
tion at a time.
Format
>n [<step>]↵ (direct input mode)
<step>: Number of steps to be executed; decimal (default is 1)
Condition: 0 ≤ step ≤ 65,535
Operation
This command basically operates in the same way as the s command.
However, the calr, calz and int instructions, including all subroutines until control returns to the next
address, are executed as one step.
Notes
• The step count must be specified within the range of 0 to 65,535. An error results if the limit is ex-
ceeded.
Error : Number of steps out of range, use 0-65535
• If the [Data] window is opened, its display contents are updated after the execution.
•During a single-step operation, the program will not break even if the break condition set by a
command is met.
• Unlike in successive executions (g or gr command), the [Register] window is updated every time a
step is executed.
