mk60dn512 low voltage warning

}

We do not appear to be generating Low-Voltage Warning Interrupts

Hi liu,

Test the code with SDK_2.2_MK60DN512xxx10 on TWR-K60D100M board.

It generat Low-Voltage Warning Interrupts.

The PTB23 can output low voltage and Blue LED can light.

You can test the project attached. (...\SDK_2.2_MK60DN512xxx10\boards\twrk60d100m\user_apps\driver_examples-uart\interrupt)

Best Regards,

Robin
