Other Parts Discussed in Thread: MSP430F5435

Sir I want to know what is the default frequency of MSP430F5435. I have been through datasheet and it says the SMCLK,MCLK are sourced by DCO by default. I want to know whats the default frequency of this DCO. And how can I change it.

Waiting for fast reply !

Thank You

    Default DCO frequency (at startup) is close to 1 MHz.

    ACLK = REFO = ~32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz

    How it can be changed is explained in MSP430F5435 datasheet and TI source code examples for MSP430F5xx family.
