To select if there will be a keep-alive function, its
address, and function code
•
Choose "Yes" or "No" for the "Enable Keep Alive Function" configuration option
(available for use with the background monitor).
Choosing "Yes" specifies that a selected address will be read by the background
monitor periodically. You must also specify the address to be read, and the
function code used when reading that address, as follows:
•
Choose "Super" or "User" for the "Keep Alive Function Code" configuration
option. This determines whether the supervisor function code or the user
function code will be used when the emulator reads the keep-alive address.
•
Type in the keep-alive address in the text entry area beside "Keep Alive
Address". This address in target memory will be read periodically during
background monitor execution. The read accesses to the target memory
address can be used to avoid a timeout of a target system bus or a watchdog
timer during background monitor execution.
Choosing "No" specifies that there will be no keep-alive memory read cycles in
target memory during background monitor operation.
