MSP430G2402: I have a question about external clock input of MSP430G2xx series.

Expert 2780 points
Part Number: MSP430G2402

Hello,


The MSP430G2xx supports External Digital Clock Source.
When an external clock is input to XIN (P2.6), can P2.7 (XOUT) be used as GPIO?

Also, when I checked the data sheet, I found in the explanation of P 2.7
that the Pin Functions table is different even though the Pin Schematic is the same.
Which is correct?

  • Hi,

    1. P2.7 (XOUT) can be used as GPIO, when an external clock is input to XIN (P2.6).

    2. Sorry for confusing you with the mistake of Table22 of MSP430G2x53 Datasheet. It should be P2SEL.6=X and P2SEL.7=0 for P2.7 configured to I/O function. We will update the datasheet for next version.
