Error Codes and Alarms
8.1 Watchdog
It is possible to use on-chip hardware watchdog timer to recover software dead-
locks. Watchdog timer can be enabled in
device_parameters #99
(Watchdog_enable) . Watchdog timer timeout is fixed to 5 seconds.
8.2 Error codes
There are following general error codes defined. Errors are inserted to the error
code word bit by bit. Each error corresponds one bit so totally 16 errors can be
defined. Error code is read by UI in diagnostics tab.
Errors are cleared automatically if they disappear. Watchdog error is only cleared
by powering down the resonator.
Error types in error code can’t be masked. All error types are always active. In other
hand errors which generate alarm can be defined.
