Other Parts Discussed in Thread: TPS3430

HI,

We need one  clarification,

Our design we have used Watchdog IC (TPS3430WDRCR), Watchdog output from Watchdog IC we have given B14 pin,

Is it right pin mapping? 

Could you please suggest. 

Thanks and Regards,

Ganesh V

    Hi Ganesh,

    The TPS3430 features a programmable window watchdog timer with an programmable watchdog output (WDO). The watchdog output can flag a fault whenever the watchdog input is outside of the watchdog window. When WDO is not asserted (high), the WDO signal maintains normal operation. When asserted, WDO remains down for tRST and WDI is ignored during the watchdog reset delay. When the watchdog is disabled, WDO remains high regardless of WDI.

    nERROR is an output signal on TMS570 device. The nERROR is triggered when a fault is detected. The WDO of TPS3430 should not be connected to RM48 nERROR pin.

    You can connect TPS3430 WDO to one of RM48 GIO pins. The RM48 has 16 dedicated GPIO pins with external interrupt capability.
