Section 28 Power-Down Modes
28.9
28.9.1
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 consumption. Data in the on-chip RAM is not retained because the
internal power supply to the on-chip RAM stops. I/O ports are set to the high-impedance state.
Do not change the states of mode pins (MD3 to MD0) while this LSI is in hardware standby mode.
28.9.2
Hardware standby mode is cleared by means of the STBY pin and the RES pin. When the STBY
pin is driven high while the RES pin is low, the reset state is entered and clock oscillation is
started. Ensure that the RES pin is held low until clock oscillation settles (for details on the
oscillation settling time, refer to table 28.2). When the RES pin is subsequently driven high, a
transition is made to the program execution state via the reset exception handling state.
28.9.3
Figure 28.8 shows an example of hardware standby mode timing.
When the STBY pin is driven low after the RES pin has been driven low, a transition is made to
hardware standby mode. Hardware standby mode is cleared by driving the STBY pin high,
waiting for the oscillation settling time, then changing the RES pin from low to high.
