Hello,
I have hard times to understand what the datasheet is trying to interpret in
timings for reset from different state of the AVR ATTiny13A.
Particularly I am interested when the internal RC oscillator is used for
clocking the chip. As I understood I can set up different delay when comes
up from powered down mode. It ads additional 14 CK to the 6 CK normal
start-up time + can set further 4ms or 64ms.
What is not clear when is this delay added to the normal start-up time? Only
at POR, or also when waking up from power down sleep mode? Also could not
figure out from the datasheet the timing of waking up the MCU from idle
mode?
In addition to this grey cloud I could not find information of this 6 CK
startup time? I guess ones the oscillator is up and stable then it counts to
6 and this is this this 6 CK startup time, but how long does it take to the
oscillator circuit to be started up into a stable condition when this 6 CK
starts counting? Especially regarding this to different thermal and power
supply conditions?
If you could point me to a link or which documentation shall I read on this
subject, it would be much appreciated.
Thanks,
Tamas
