Storage Temperature
VDDIO can be applied to PSWITCH through a 10 kΩ resistor. This is necessary in order to enter the chip’s firmware recovery
mode. (The on-chip circuitry prevents the actual voltage on the pin from exceeding acceptable levels.)
Application should include a Schottky diode between BATT and VDD4P2.
USB_DN and USB_DP can tolerate 5V for up to 24 hours. Note that while 5V is applied to USB_DN or USB_DP, LRADC
readings can be corrupted.
