1.3.5.1 NORMAL Mode
In normal mode, all peripherals and the basic blocks including power management block, the CPU core, the bus
controller, the memory controller, the interrupt controller, DMA, and the external master may operate fully. But,
the clock to each peripheral, except the basic blocks, can be stopped selectively by software to reduce the power
consumption.
1.3.5.2 POWER_OFF Mode
The block disconnects the internal power. So, there occurs no power consumption due to CPU and the internal
logic except the wake-up logic in this mode. Activating the Power-OFF mode requires two independent power
sources. One of the two power sources supplies the power for the wake-up logic. The other one supplies other
internal logics including CPU, and should be controlled for power on/off. In the Power-OFF mode, the second
power supply source for the CPU and internal logics will be turned off. The wakeup from Power-OFF mode can be
issued by the EINT[15:0] or by RTC alarm interrupt.
