XMEGA B1 [DATASHEET]
Atmel-8330H-AVR-ATxmega64B1-128B1_datasheet–AVR–12/2014
Notes: 1. All parameters measured as the difference in current consumption between module enabled and disabled. All data at V
CC
= 3.0V, Clk
SYS
= 1MHz External clock
without prescaling, T = 25°C unless other conditions 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 74. 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.
