MSP430G2553: msp430g2553 imterupt

Binh Nguyen Thanh94

Part Number: MSP430G2553

Hi everyone,

I am using an msp430g2553 MCU in my circuit. I want to use its interupt function which will be activated by the output of an analog sensor. However, I can't find information about the minimum voltage required at the MCU pin to be recognized and to enter an interupt event. Please help me, thanks a lot!!!

Sincerely,

Binh Nguyen Thanh

Hi Binh Nguyen Thanh,

1. You can use the COMP to make the comparison.

2. If you need to find the IO pin spec, see below.

Hi Binh Nguyen Thanh,

Sorry, the data spec capture is lost in the previous reply. Re-attach it here. You can find it in 5.13.5 General-Purpose I/Os chapter in the datasheet.

Best regards,

Hi Jovi He,

Thanks for your help, but the image is still invisible. I also don't see the datasheet file which has the section you mentioned. Could you please give me the link? thank you.

Sincerely,

Hi Binh Nguyen Thanh,

Here is the link to the datasheet and you can find the IO input characteristics in page 24.
The 5.13.5 General-Purpose I/Os chapter mentioned was from another datasheet. sorry for this.
