    RE: MSP430FR5872: Watchdog Reset occurs but SYSRSTIV does not show reset cause correctly

    Hey Aman, I think what might be happening is that you are somehow running into nested reset interrupts. This is discussed a bit in section 1.3.7 of the Family User's Guide: http://www.ti.com/lit/ug/slau367o/slau367o.pdf When you read SYSRSTIV...

    RE: MSP430FR5872: LPM4.5 Wakeup

    Himanshu Khanna I was configuring P9.7 high after clearing the LOCKLPM5 bit. This is probably the cause of this issue. When you exit LPM4.5 and go through the reset, the Digital IO register contents are reset to default values (Hi-Z inputs in most cases...

    RE: MSP430FR5872: On Chip Temperature Sensor

    Short answer: If you truly want to sample multiple channels Continuously ("as fast as it can"), use CONSEQ=3 [Ref SLAU367O sec 34.2.8.4; there's a lot of information in Fig 34-11]. I hesitate to recommend CONSEQ=3 since (1) "as fast...

    RE: CCS/MSP430FR5872: Error initializing emulator: The voltage 1469 value is not correct/allowed for the USB FET

    Another engineer saw immediately that I had power connected incorrectly, and the custom board battery protection circuit had cut off power on the target board. Fixed the connection, and the problem is resolved. As I suspected - user error. Thanks...

    RE: CCS/MSP430FR5872: Location of mpu_ctl0_value clashes with other things

    Hi Thomas, The mpu_ctl0_value is the initial value that will be programmed in MPU (Memory Protection Unit) register. It is the default value for the register. I would suggest to keep it. If you would like to know the details of it this is the best...

    RE: MSP430FR5872: Data Sheet errata - Interrupts on 'all' ports

    Hello Tim, Yes, only ports 1-4 on this device have interrupt capability. This is also stated in a statement below the one you pointed out. *Edge-selectable interrupt and LPM3.5 and LPM4.5 wakeup input capability is available for all pins of ports...

    RE: Strange GPIO problem with MSP430FR5872

    Hello Salvatore, From a coding standpoint, you are toggling the GPIOs correctly; however, with our FRAM devices, after POR you need to add the following line to unlock the GPIOs after you configure them. PM5CTL0 &= ~LOCKLPM5; // Disable the...
