The ZSOM-Mini does not boot up automatically, when power is applied. The Go input can be used together with a push button to wake up ZSOM-Mini.
ZSOM-Mini will boot as soon as the Go input (pin 1) is tied to GND (eg. pin 2) for more than 50ms.
The ZSOM-Mini can be alternatively woken up by the RTC
ZSOM-Mini will cut the power to the core and the preipherals when the Go input (pin 1) is tied to GND (eg. pin 2) for more than 5s.
The power of the ZSOM-Mini can be alternatively be cut via the Kill signal in the FPGA
The functionality of the Go input, the RTC wakeup and the FPGA Kill signal can be overwritten with the Always on jumper
