Question
STM8AL3189TCX NRST pin is asserted what happens to MCU output
Hello All,
we are using STM8AL3189TCX MCU in our design to control the system.
A WDT signal "MCU_NRST" is connected to NRST(PIN-2, NRST/PA1) pin in microcontroller with a Pull up to 3V3.
What will happen to MCU IC when the below reset condition occur:
Condition:- If WDI pulse from HOST MCU fails this condition (Lower Boundary (tWDLmin) = 19.1ms-25.6ms & Upper Boundery (tWDUmax) = 46.8-63.3ms)
HW Action:- Supervisor will asserted low to reset, HOST MCU to turn off the system
Is the hardware action mentioned is correct?
