Error state logging
3.4.1
Watchdog
The watchdog device monitors the CPU board on operating system level. If enabled, the
watchdog must be triggered by application software. If the trigger is overdue, the
watchdog initiates a board reset and in this way can put the system back into operation
when the software hangs.
The watchdog unit can be enabled or disabled, as required and the watchdog timeout
can be set in 100-ms steps from 100 ms up to 1:49:10 (hh:mm:ss) - 65536 steps.
3.4.2
Temperature Measurement
The BL70S uses a temperature device to measure the local CPU board temperature.
