Table 10. ATtiny12 Clock Options and Start-up Times
Note:
This table shows the start-up times from reset. From sleep, only the clock counting part
of the start-up time is used. The Watchdog oscillator is used for timing the real-time part
of the start-up time. The number of WDT oscillator cycles used for each time-out is
shown in Table 11.
Table 11. Number of Watchdog Oscillator Cycles
The frequency of the watchdog oscillator is voltage dependent as shown in the section
“ATtiny11 Typical Characteristics” on page 62.
Note that the BODLEVEL fuse can be used to select start-up times even if the Brown-
out Detection is disabled (by leaving the BODEN fuse unprogrammed).
The device is shipped with CKSEL3..0 = 0010.

1. Due to the limited number of clock cycles in the start-up period, it is recommended
that Ceramic Resonator be used.
