Refresh
Select the Refresh menu entry to refresh the Memory window current data cache. The
debugger refreshes the data cache as if the debugger was halted or stepped.
Note that only memory ranges defined with the Refresh memory when halting option in
the Debugging Memory Map (DMM) interface are refreshed. The Refresh menu entry
addresses, by DMM factory setup, the volatile memory, i.e. the RAM and on-chip I/O
Registers.
TIP To refresh other memory ranges, either set the Refresh memory when halting
option for wanted ranges in the DMM dialog, or type/enter the DMM
RELEASECACHES command in the Command window. You can disable caching
for the debug session when typing/entering the DMM CACHINGOFF command in
the Command window.
Update Rate
This dialog box, shown in Figure 3.43, allows you to modify the update rate in steps of
100ms.

NOTE Periodical mode is not available for all hardware connections or some
additional configuration may be required in order to make it work.
When you check the Refresh memory periodically when halted checkbox, the debugger
keeps on refreshing caches even when it is not running. This allows you to see I/O
Register changes even if the CPU is not running.
