Hello,

For TC36x microcontrollers, in the datasheet for MHz oscillator there are internal load capacitors as in below snap -

What is the significance of these capacitors? These internal load caps are between XTAL1 & XTAL2 pins ?

While selecting crystal or resonator, do we have to enable the above load caps in above snaps.

If these caps are not enabled, then what is the default load capacitor value?

If we select the the resonator with integrated load cap of 15pF, what internal load cap value needed ??
