asynchronous timer should be considered undefined after wake-up in Power-save mode
if AS0 is 0.
This sleep mode basically halts all clocks except clk
chronous modules, including Timer/Counter0 if clocked asynchronously.
When the SM2..0 bits are 110 and an External Crystal/Resonator clock option is
selected, the SLEEP instruction makes the MCU enter Standby mode. This mode is
identical to Power-down with the exception that the Oscillator is kept running. From
Standby mode, the device wakes up in 6 clock cycles.
When the SM2..0 bits are 111 and an external crystal/resonator clock option is selected,
the SLEEP instruction makes the MCU enter Extended Standby mode. This mode is
identical to Power-save mode with the exception that the Oscillator is kept running.
From Extended Standby mode, the device wakes up in six clock cycles.
