The F243/F241 devices include a watchdog (WD) timer module. The WD function of this module monitors software and hardware operation by generating a system reset if it is not periodically serviced by software by having the correct key written.

The WD timer operates independently of the CPU and is always enabled. It does not need any CPU initialization to function when extract code from dsp controller tms320f241pga. When a system reset occurs, the WD timer defaults to the fastest WD timer rate available (6.55 ms for a 39 062.5-Hz WDCLK signal).

As soon as reset is released internally, the CPU starts executing code, and the WD timer begins incrementing. This means that, to avoid a premature reset, WD setup should occur early in the power-up sequence. See Figure 15 for a block diagram of the WD module. The WD module features include the following:

  • WD Timer

−    Seven different WD overflow rates ranging from 6.55 ms to 419.43 ms

−    A WD-reset key (WDKEY) register that clears the WD counter when a correct value is written, and generates a system reset if an incorrect value is written to the register

−    WD check bits that initiate a system reset if an incorrect value is written to the WD control register (WDCR) by tms320f241pga dsp microcontroller flash program duplication;

  • Automatic activation of the WD timer, once system reset is released

−     Three WD control registers located in control register frame beginning at address 7020h.
