Section 22 Power-Down Modes
Bit 7—Direct Transition ON Flag (DTON): When shifting to low power dissipation mode by
executing the SLEEP instruction, this bit specifies whether or not to make a direct transition
between high-speed mode or medium-speed mode and the subactive modes. The selected
operating mode after executing the SLEEP instruction is determined by the combination of other
control bits.
Note: * Always set high-speed mode when shifting to watch mode or subactive mode.
Bit 6—Low-Speed ON Flag (LSON): When shifting to low power dissipation mode by executing
the SLEEP instruction, this bit specifies the operating mode, in combination with other control
bits. This bit also controls whether to shift to high-speed mode or subactive mode when watch
mode is cancelled.
Note: * Always set high-speed mode when shifting to watch mode or subactive mode.

When the SLEEP instruction is executed in high-speed mode or medium-speed
mode, operation shifts to sleep mode, software standby mode, or watch mode * .
When the SLEEP instruction is executed in subactive mode, operation shifts
to subsleep mode or watch mode.
When the SLEEP instruction is executed in high-speed mode or medium-speed
mode, operation shifts directly to subactive mode * , or shifts to sleep mode or
software standby mode.
When the SLEEP instruction is executed in subactive mode, operation shifts directly
to high-speed mode, or shifts to subsleep mode.
When the SLEEP instruction is executed in high-speed mode or medium-speed
mode, operation shifts to sleep mode, software standby mode, or watch mode * .
When the SLEEP instruction is executed in subactive mode, operation shifts to watch
mode or shifts directly to high-speed mode.
Operation shifts to high-speed mode when watch mode is cancelled. (Initial value)
When the SLEEP instruction is executed in high-speed mode, operation shifts to
watch mode or subactive mode.
When the SLEEP instruction is executed in subactive mode, operation shifts to
subsleep mode or watch mode.
Operation shifts to subactive mode when watch mode is cancelled.
