+ Sleep "Deeper" Mode (High Power Savings) - This mode reduces dynamic
+ power dissipation by disabling the clock to the processor core (CCLK).
+ Furthermore, Standby sets the internal power supply voltage (VDDINT)
+ to 0.85 V to provide the greatest power savings, while preserving the
+ processor state.
+ The PLL and system clock (SCLK) continue to operate at a very low
+ frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
+ the SDRAM is put into Self Refresh Mode. Typically an external event
+ such as GPIO interrupt or RTC activity wakes up the processor.
+ Various Peripherals such as UART, SPORT, PPI may not function as
+ normal during Sleep Deeper, due to the reduced SCLK frequency.
+ When in the sleep mode, system DMA access to L1 memory is not supported.
