Programming controller with out external crystal or clock

[NAIDU]

Can I program MPC5777C Controller with out any external crystal or oscillator?I mean by using internal RC oscillator?

Hello,

yes, it is possible to use internal RC oscillator only, but remember, that external crystal has much better parameters like jitter etc.

You can also use MPC5777C clock configurator which helps you to set all clocks.
