Starting
6.4.1
Starting from Reset
The internal reset is immediately asserted when a reset source goes active. The internal reset is kept asserted until
the reset source is released and the start-up sequence is completed. The start-up sequence includes three steps,
as follows.
1.
The first step after the reset source has been released consists of the device counting the reset start-up
time. The purpose of this reset start-up time is to ensure that supply voltage has reached sufficient levels.
The reset start-up time is counted using the internal 128 kHz oscillator. See Table 6-1 for details of reset
start-up time.
Note that the actual supply voltage is not monitored by the start-up logic. The device will count until the
reset start-up time has elapsed even if the device has reached sufficient supply voltage levels earlier.
2.
The second step is to count the oscillator start-up time, which ensures that the calibrated internal oscillator
has reached a stable state before it is used by the other parts of the system. The calibrated internal oscil-
lator needs to oscillate for a minimum number of cycles before it can be considered stable. See Table 6-1
for details of the oscillator start-up time.
3.
The last step before releasing the internal reset is to load the calibration and the configuration values from
the Non-Volatile Memory to configure the device properly. The configuration time is listed in Table 6-1.
Notes:
1. After powering up the device or after a reset the system clock is automatically set to calibrated internal 8 MHz oscil-
lator, divided by 8
6.4.2
Starting from Power-Down Mode
When waking up from Power-Down sleep mode, the supply voltage is assumed to be at a sufficient level and only
the oscillator start-up time is counted to ensure the stable operation of the oscillator. The oscillator start-up time is
counted on the selected main clock, and the start-up time depends on the clock selected. See Table 6-2 for details.
Notes:
1. The start-up time is measured in main clock oscillator cycles.
6.4.3
Starting from Idle / ADC Noise Reduction / Standby Mode
When waking up from Idle, ADC Noise Reduction or Standby Mode, the oscillator is already running and no oscilla-
tor start-up time is introduced.
The ADC is available in ATtiny5/10, only.
