What kind of power modes does EVE support?

There are 4 power modes that EVE supports.

1. Active state – EVE is in full function mode preforming graphic rendering, touch processing and audio processing.
2. Standby state – in this state, the crystal oscillator and PLL are functioning, the system clock to EVE’s core is disabled. All register content is retained.
3. Sleep state – in this state, the crystal oscillator and PLL is disabled, the system clock applied to EVE’s core is disabled. All register content is retained.
4. Power down state – in this state, the internal 1.2V regulator supplying the core digital logic is disabled. The crystal oscillator and PLL is disabled, and the system clock applied to EVE’s core is disabled. All register contents are lost and reset to default upon power on reset.
