3.12 Reset buttons

Two buttons, SW500 and SW501, can be used to reset the JODY-W3 module and the whole EVB,
respectively.
Button SW500 asserts the PD# pin of the JODY-W3 module to enter power down mode, while keeping
the supply rails enabled. When exiting the power-down mode, the module is automatically reset and
the firmware must be downloaded again.
Button SW501 causes all the module supply rails from the on-board Power Management Unit (PMU)
to shut down. Internal power-on reset of the module is triggered when the button is released, which
restores power to the module.
