Notes:
1. .All parameters measured as the difference in current consumption between module enabled and disabled. All data at V_CC = 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.

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 72. 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.
