Part Number: MSP430F5418

My customer have some questions about the Low power mode of MSP430F5418AIPN:

1. how to trigger low power mode.

2. It is mentioned in the data that low power mode requires external interrupt processing. How to configure the I/O ports of P1 and P2 is not explained.

    Hi,

    thanks for posting this question here.

    The best way to get started on this topic could be to have a look at our code examples. The TI Resource Explorer includes example code and documentation for our different devices, browse to the MSP430F5418 and check for code examples. We provide examples for both the low-power modes (LPM) as well as port interrupts.

    Setting the LPM is fairly easy done in software. Keep in mind that the LPM are tied to the different clocks that are available. Make sure that none of the active modules require a clock that is disabled in the according LPM as this would prevent the MCU to actually enter the desired LPM. This behaviour is documented in the device family User's Guide. You also should find information on Port interrupts in the User's Guide.This is covered in the Digital I/O Module section.

    Note that the MSP430F5418 is not recommended for new designs. We recommend to use the MSP430F5418A instead, which acts as a replacement for the non-A version. Please consider to move to the MSP430F5418A and check the according code examples.

    Let me no if you have additional questions.

    Best regards,

    Britta
