Hi NXP Team,
We are using Rt1176 MCU in our custom board.the wake up pin connected to NOR gate output and NOR gate input will be 2 Digital inputs where MCU should wake up when the digital inputs are High.
In EVK the wake up pin is connected to switch and acts as trigger input.
In our custom board the NOR gate output will remains low until the Digital inputs are low. Is this ok to leave wake up at low state after MCU wakeup?
Attached is the Schematics of wake up pin circuit.
Solved! Go to Solution.
Hi @Chethanbg ,
In fact, no matter how you connect.
If your WAKEUP pin is low, it will wakeup the chip from the low power mode, so I think, your situation is the same as the EVK, it can wakeup the chip.
Wish it helps you!
If you still have question about it, please kindly let me know.
Best Regards,
Kerry
