5.1.3 S1 HRESET Push-Button
S1 is located on the top-left corner of the EVM. This switch is a push-button that pulls the HRESET pin (39) of
the TPS65988 high when pressed. Releasing the push-button pulls HRESET low again, and the TPS65988 goes
through a soft reset, which consists of reloading firmware (FW) from RAM. If a
valid
configuration is present in
the RAM, the TPS65988 does not reload the configuration from the external flash.
