36.3.4 Wake-up time from sleep modes
Table 36-70. 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. 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.
