1 GND Ground. Ground. 2 GPIO3 Digital Driving this pin high during bootup wil put the Input Low module in Device Firmware Update (DFU) mode. The device wil enter DFU mode in 3 seconds. The pin should only be asserted high before the device enters DFU mode and not after. (USB device powers VBUS. PIO3 requires 47K to ground and 22K to USB VBUS if USB VBUS is supplying power to the main board.) During runtime, if the pin is driven high, the device will reset and reboot. Note: Device will reset within 500 ms after the IO is driven high. A reset pulse of 100 ms is recom- mended. If IO continues to be driven high after reset, the device will naturally enter DFU mode. The device wil enter DFU mode in 3 seconds. 3 GPIO2 Digital Reserved, event indicator pin. A microcontroller Output High can enter Command mode and poll the state register using the Q action command 4 AIO0 Bidirectional Analog programmable input/output line I/O DS70005120A-page 4  2015 Microchip Technology Inc.
