Evaluation Kit User Guide
TIMING CONSIDERATIONS WHEN DEBUGGING
UG-041
Other timing considerations to keep in mind are as follows:
As with other 8052-based parts, the watchdog on ADuC8xx
parts is not stopped during debugging. This leads to unpre-
dictable results when the watchdog timer times out. During
initial development, it is recommended that the watchdog timer
be left disabled. For final software, Analog Devices suggests that
you include code similar to the code that follows.
When debugging, place a breakpoint at the second line shown, and
when this breakpoint is reached manually, using the debugger,
change the value in cWdcon to 0x00 so that the watchdog does
not start. This scheme ensures that the program is debugged as
it will be placed in the field. The watchdog itself cannot be
debugged by the debugger.

?
As with other 8052-based debuggers, the user should not halt
the ADuC8xx if the part is either in idle or power-down
mode. When a break from either power saving mode
occurs, the debugger will not be able to regain control of
the part and the debug interface will crash.
The timers on the ADuC8xx are not stopped on a break
from emulation. They continue to run if left enabled when
breaking from emulation.
cWdcon = 0xe2 ;
WdWr(cWdcon);

cWdcon:
//Place parameters for watchdog in variable cWdcon.
//Call assembly function to start watchdog.
//Assume interrupts not enabled.
