Tool/software:
hi team !
for TPS 929240 new version datasheet, i noticed the change point that the "watchdog timer starts to count when uart bus is idle"
plz help give more explain or background information why have such modifications?
one more question about applications:
e.g. 2 kinds of different functions used several tps240s and share same uart bus. safety goal: one of function failure not be allowed to influence anothers.
if one of tps240 chip happened failure, controller have to idle whole uart bus, then device can switch to fail-safe mode. in this case another function will be influenced since bus idle.
is there any suggestion for it?
