CCS/MSP430F2617: Initialising Digital I/O ports on lower pin count devices?

Raymond Wales

Part Number: MSP430F2617

Tool/software: Code Composer Studio

The MSP430F241x and 261x are available in 64 or 80 pin packages.

In the 64-pin variants, Digital I/O ports P7 and P8 are not implemented.

When compiling code for these lower pin count devices, CCS Low Power Advisor complains that P7 and P8 have not been initialised.

Is it advisable (or even possible) to initialise these ports and set them to output mode?

Thanks - Ray

Hi Ray,

Yes, set them to output low can save power.

Thank you Ling - and specially for answering so quickly.

This issue is not clear in the documentation.

I had consulted both the device data sheet (slas541) and the Family User Guide (slau144).
