Hi, I was working on interfacing my MSP430 with a 4x4 keypad and I stumbled upon this application report. Then I looked into the specific low power modes of the F5529 and noticed that there was a LPM4.5. The application report uses LPM4 as it isn't the same device, and I was wondering if it was possible to use LPM4.5 as the device was waiting for keypad input as my goal is to minimize power usage.
