An important part of a reliable system is having a reliable clock. Just like on the Piccolo devices, Concerto has missing clock detection logic. For the Concerto family, if the clock fails, it will automatically switch to the internal 10 MHz oscillator and has the option to be able to trip the PWMs using trips on PHY, so very similar to Piccolo in that respect. Then what happens is that an NMI is generated, so the two NMI Watchdog counters on the device will start counting and if the C28 responds to its Watchdog counter, it can handle the error and go into standby mode. If it doesn’t respond to it, eventually the Watchdog counter is going to timeout and it is going to reset the control system. The same thing could happen on the M3 side of things. If the M3 does respond, otherwise it is going to the Watchdog counter, the NMI Watchdog timer will time out and cause the device reset. Again, this is showing how the M3’s on the master side, C28’s on the control side, the C28 NMI Watchdog counter times out, it will just reset the control side of the device where the M3 of the M3’s NMI Watchdog counter times out, it will cause an entire device reset.
