FILE: dcc_ex3_continuous_monitoring_of_clock.c
This program demonstrates continuous monitoring of PLL Clock in the system using INTOSC1 as the reference clock. This would trigger an error signal on any error, causing the decrement/ reload of counters to stop. The Dual-Clock Comparator Module 1 is used for the clock monitoring. The clocksource0 is the reference clock (Fclk0 = 10Mhz) and the clocksource1 is the clock that needs to be monitored (Fclk1 = 200Mhz). The clock0 and clock1 seed are set automatically by the error tolerances defined in the sysconfig file included in this project. For the sake of demo an un-realistic tolerance is assumed to generate an error on continuous monitoring.
Please refer to the TRM for details on counter seed values to be set. Note : When running in flash configuration it is good to do a reset & restart after loading the example to remove any stale flags/states.
