Power Control
2.15.4 Precautions in Power Control
(1) The processor does not switch to stop mode when the NMI pin is at “L” level.
(2) When returning from stop mode by hardware reset, RESET pin must be set to “L” level until
(3) When switching to either wait mode or stop mode, instructions occupying four bytes either

NOPs in succession either to the WAIT instruction or to the instruction that sets the all clock

software for the oscillation to stabilize before switching over the clock.

The processor retains the state of each programmable I/O port even when it goes to
wait mode or to stop mode. A current flows in active I/O ports. A pass current flows in
input ports that float. When entering wait mode or stop mode, set non-used ports to
input and stabilize the potential.
A current always flows in the V

The processor retains the D-A state even when entering wait mode or stop mode.
Disable the output from the D-A converter then work on the programmable I/O ports.
Set D-A register to “00
In wait mode, stop non-used peripheral functions using the WAIT peripheral function

low-speed or low power dissipation mode, do not enter WAIT mode with this bit set to
“1”.
Set the driving capacity to “LOW” when oscillation is stable.
When using an external clock input for the CPU clock, set the main clock stop bit to
“1”. Setting the main clock stop bit to “1” causes the X
power consumption goes down (when using an external clock input, the clock signal
is input regardless of the content of the main clock stop bit).
