HALT Command
HALT Command
The HALT command halts the processor. The form of the HALT command is:
Considerations
•
The HALT command is allowed only if you are debugging in privileged mode as
described under the PRV command.
•
Any running processors will declare the halted processor as being down.
•
Once a processor is halted, a service provider can use the service processor (SP)
to examine the processor.
Example
245,02,00033-HALT ! Halts the current processor, 02 in this example.
H[ELP] Command
The HELP (or H) command displays help information about Debug commands. The
form of the HELP command is:
debug-command
specifies the command whose syntax Debug is to display.
<variable-item>
specifies a variable item whose syntax Debug is to display. A variable item
represents an item that you supply in a Debug command. The values you can
specify for variable-item might vary depending on the release of Debug that
you are using.
The variable-item parameter must be enclosed in angle brackets.
You can specify either debug-command or <variable-item>, but not both. If you
omit both debug-command and <variable-item>, Debug displays all the available
Debug commands and variables. Privileged Debug commands and options appear
only if you are debugging in privileged mode as described under the PRV command.
