Troubleshooting

Troubleshooting:

 CAN-ID 0 - Bug:
 - Workaround 1: Use an even number of CAN receive blocks (regardless of whether 11 or 29 Bit)
 - Workaround 2: Use a CAN-Rx block (11 Bit) with ID 0 or 0x000

 High Resolution-PWM - Bug:
 - Workaround: The PWM output can be initialized by the correct single usage of the normal PWM block. Then, the usage of the high resolution PWM is possible.

Timer racing condition - Bug (with 16bit Controller):
 - Recommendation: no usage of the time blocks in critical application (Problem occurs only very rarely, but is not excluded)
 - Workaround: replacement of the time function by replication with blocks over counting of application cycles

 Timer-Init-Bug (time 0.1% too long):
 - Workaround: Adjustment of time values to 99.9 percent of the actual value
 - Note: Task cycle time only conditionally correctable
 - Assessment: effect notable only during long-term measurements
