Low-Power Modes
External reset — A logic 0 on the RESET pin resets the MCU and
loads the program counter with the contents of locations $1FFE
and $1FFF. The timer begins counting from $FFFC.
When the MCU exits stop mode, processing resumes after a
stabilization delay of 4064 oscillator cycles.
An active edge on the PD7/TCAP pin during stop mode sets the ICF flag
when an external interrupt brings the MCU out of stop mode. An external
interrupt also latches the value in the timer registers into the input
capture registers.
If a reset brings the MCU out of stop mode, then an active edge on the
PD7/TCAP pin during stop mode has no effect on the ICF flag or the
input capture registers.
See Figure 24 for stop recovery timing information.
