MSP430FR5989: Port P9 interrupt available to use

Michal Wolowik

Hello,

my question is very easy. Do it possible to use P9.6 and P9.7 as an inputs edge interrupt triggered? Documentation confirms that such activity is possible and register exist (P9IE). Unfortunately, in a code, I can't find an interrupt vector for PORT9 and P9IE as well. I have a strange feeling that it is impossible. Am I right? In some thread on this forum, I found that for MSP432 it is impossible but my core is different.

The documentation I used is slau367o MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide (page 375 - bottom)

Thanks in advanced

The User Guide describes the union of all features that appear in any of the devices in that series.

You should also keep handy the Data Sheet (in this case SLAS789D, available at the top of the Product page) for your particular device. In the Data Sheet (Table 6-60) P9IE is notable by its absence.
