Compiler/MSP430FR6972: What gets cleared when watchdog resets?

Part Number: MSP430FR6972

Tool/software: TI C/C++ Compiler

Hi,

      Do the ram and registers be cleared when the watch dog reseting ?   For example, if this is some wrongs in ADC's register,  could the watch dog reseting clear the ADC's wrongs and make ADC normal ?

  • Hi Jent,

    A watchdog reset is a PUC reset. It shouldn't clear the RAM content since no new power cycle. For the register's value after a PUC reset, you could find each register shown with a key indicating the accessibility, which is described in section Register Bit Conventions of the User's Guide preface, of the each individual bit and the initial condition.
