The GS1559 has a recommended power supply sequence. To ensure correct
power up, power the CORE_VDD pins before the IO_VDD pins.
Device pins may also be driven prior to power up without causing damage.
To ensure that all internal registers are cleared upon power-up, the application
layer must hold the
