3.4.1 TIMG0

Figure 3-2 shows TIMG0/8 sourced by LFCLK consumes nearly no power under STANDBY1 mode. Combining the results of RTC and WWDT power test, the peripherals driven by LFCLK consume little power when running. And it is also the reason why TIMG0 is used on LFCLK as the timer to switch power policy in other tests.
