DCO Allows Fast Reaction to Events

Interrupt

DCO

<6us

2-Speed

Startup

The screen capture shows the actual startup of an MSP430 DCO!

•In this example it can be seen that from an interrupt event the DCO is active and stable at 8MHz

in well under 6us. In fact, in this example the measured DCO startup time is actually 292ns.

•With the MSP430, clock start up is “instant-on”. It is important that the high-speed DCO not only

starts instantly, but also stabilizes instantly. Both instant-on and instant stability are important for

features like asynchronous serial communication.

•With the MSP430 DCO, no delay or 2-speed clock startup occurs. The users application has

instant access to the high-speed DCO from any operating mode.
