24.6.5
In software standby mode, I/O port states are retained. Therefore, there is no reduction in current
dissipation for the output current when a high-level signal is output.
Current dissipation increases while waiting for oscillation to settle.

24.7.1
When the STBY pin is driven low, a transition is made to hardware standby mode from any mode.
In hardware standby mode, all functions enter the reset state and stop operation, resulting in a
significant reduction in power dissipation. As long as the prescribed voltage is supplied, on-chip
RAM data is retained. I/O ports are set to the high-impedance state.
