= 3.0V, ClkSYS = 1MHz External
clock without prescaling, T = 25°C unless other conditiond are given.
2. LCD configuration: internal voltage generation, 32Hz low power frame rate, 1/3 bias, clocked by low power 32.768kHz TOSC.
36.4 Wake-up time from sleep modes
Table 36-6. Device wake-up time from sleep modes with various system clock sources.
Note: 1. The wake-up time is the time from the wake-up request is given until the peripheral clock is available on pin, see Figure 36-2 on page 75. All peripherals and
modules start execution from the first clock cycle, expect the CPU that is halted for four clock cycles before program execution starts.
