How to measure phase current when using DRV8711

Hi, I am studying the article,  "Spin It! - Get Your Own Stepper Motor BoosterPack! BOOST-DRV8711", whose webpage link is "https://e2e.ti.com/blogs_/b/motordrivecontrol/archive/2014/07/03/spin-it-get-your-own-stepper-motor-boosterpack-boost-drv8711?DCMP=mdrvblog&HQS=hval-mdbu-amd-mdrvblog-150520-drv8711boosterpack-pf-en". I hope to know, what kind of TEK digital oscilloscope and which pins of "BOOST-DRV8711 and MSP-EXP430G2" may I measure to get the current waveform? Thank you.
