In my custom project,
The CD74HC283M96 IC is used for Incrementing the input by 1 and giving the output to the STM32F4 MCU
But during the bootup of the board the output of this adder is staying at high state for nearly 1.7 seconds and coming back to low state (observed by probing the ADD0 pin)
Once the board completely boots up the output is stable. But the MCU has already assigned the IP address based on the GPIO state it has seen during the bootup.
Why is this behavior shown by the adder and how can this be resolved.
Below is the signal obtained by probing the S0 pin of the adder during the bootup.
The expectation was that S0 stays at 0 throughout the bootup process. But it stayed at logic1 for 1.7sec then came back to logic 0.
Can you please guide me regarding this.
And what might be the cause for this behavior.
Best Regards,
