TM4C1294KCPDT: Use of WDTPeriphIDx, WDTPCellIDx

HS FAE Germany
Mastermind 32950 points

Part Number: TM4C1294KCPDT

Hello,

could you explain the use of the registers WDTPeriphIDx, WDTPCellIDx?.
The TRM stated "The WDTPeriphIDn/WDTPCellIDx registers are hard-coded and the fields within the register determine the reset value." but the there is no description of the reset value.
Is there an C code example which uses these register?

Regards, Holger

    Hello Holger,

    I'll be fully honest with you... I have no better idea what those registers are for than you do. Looking at the datasheet in detail, my takeaway is that they are registers which should have been left as unidentified/reserved as they serve no purpose for applications. I've used the Watchdog timer countless times and those registers have no baring in correctly operating the peripheral.

    So in summary, there is no use case for these registers and no example code, they can be effectively disregarded. They are not required to be modified in any manner to use the Watchdog timer.

    Best Regards,
