5.2.6 The Watchdog
You can monitor your processor module with a watchdog. The watchdog gen-
erates a reset, when a signal, generated by a program code, does unexpect-
edly not arrive (see also "

System Specifications - Programming in
ADbasic
"). This reset sets the digital and analog outputs to those values, which
correspond to the configuration after power-up, normally digital 0 or 0 Volt.
Notes in relation to the Pro-Flash-Boot:
– Please pay attention to the fact that the watchdog has to be reset every
1.6s, since a longer time interval between two impulses will be inter-
preted as an error.
– The watchdog can also be used with the boot loader Pro-Flash-Boot, but
does not automatically load and start the software.
– Test your programs always with the watchdog switched off. Activate it
only when your programs work appropriately!
