2.1.2 Push Buttons

The EVM supports two buttons that provide a reset and user input to the controller.

SW1 RESET

This Switch is used to RESET the AM2732, PMIC, and FTDI device.

SW2 GPIO_28 When pushed, the GPIO_28 (net MSS_GPIO_28) is pulled high to PMICOUT_3V3.

When idle (not pushed), GPIO_28 (net MSS_GPIO_28) is pulled to ground via a 10 kilo ohm resistor.
