GPT time

[youngkin]

hello：

I config the gpt, the gpt clock is 40M. the clock is set as follow:

the mcu clock  show as follow：

and  i start the gpt(Gpt_StartTimer(GptConf_GptChannelConfiguration_GptChannelConfiguration_0, 10000000U);),   I measure GPT time ，it is 200ms。 

but i think the gpt time should be 250ms（（1/40000000）   * 10000000 = 250ms）.

Please take some time to help answer, thank you

How to confirm that the clock source currently being used is an external crystal oscillator(16M)? Currently, the GPT clock is not 40M, it seems 50M.
