LPC5410x : Clock Cross-Check

Is there a quick (and relatively easy) way using the LPCopen libraries to cross-check the rate of an external clock with that of an internal clock (e.g. IR or RTC)? This would be part of a power-up self-test to ensure that the rate of the external clock is within tolerance (or at least that it is relatively consistent with the internal clock(s)).

Hi,

There is a way to monitor some clocks by using CLKOUT pin. Using this feature you can select and observe certain clocks through an external pin.
