CCS/MSP430F5418A: How to initialize PORTE and PORTF?

Mechi Fendel

Part Number: MSP430F5418A

Tool/software: Code Composer Studio

After compilation I receive the following ULP remarks:

remark #10372-D: (ULP 4.1) Detected uninitialized Port E in this project. Recommend initializing all unused ports to eliminate wasted current consumption on unused pins.

remark #10372-D: (ULP 4.1) Detected uninitialized Port F in this project. Recommend initializing all unused ports to eliminate wasted current consumption on unused pins.

In the data sheet, just PORTA-D are shown in the Functional Block Diagram. How can these ports be initialized?

Thanks,

Hello,

This is the general ULP(Ultra-Low-Power) Advice for all packages. You don't need to initialize PortE&PortF.

Ignoring the ULP advice doesn't impact the correct perform of code, only may not obtain the best power consumption performance.

I guess this is the answer - but I still would like to "initialize" these "phantom" PORTs so as not to get all of the ULP comments...

Thanks,

Mechi
