Bit 7

DTON

Description

When a SLEEP instruction is executed in high-speed mode or medium-speed mode,

a transition is made to sleep mode, software standby mode, or watch mode*

When a SLEEP instruction is executed in subactive mode, a transition is made to

subsleep mode or watch mode

(Initial value)

When a SLEEP instruction is executed in high-speed mode or medium-speed mode,

a transition is made directly to subactive mode*, or a transition is made to sleep mode

or software standby mode

When a SLEEP instruction is executed in subactive mode, a transition is made directly

to high-speed mode, or a transition is made to subsleep mode

Note:

When a transition is made to watch mode or subactive mode, high-speed mode must

be set.

Bit 6—Low-Speed On Flag (LSON): Determines the operating mode in combination with other

control bits when making a power-down transition by executing a SLEEP instruction. Also

controls whether a transition is made to high-speed mode or to subactive mode when watch mode

is cleared.

Bit 6

LSON

Description

When a SLEEP instruction is executed in high-speed mode or medium-speed mode,

a transition is made to sleep mode, software standby mode, or watch mode*

When a SLEEP instruction is executed in subactive mode, a transition is made to

watch mode, or directly to high-speed mode

After watch mode is cleared, a transition is made to high-speed mode

(Initial value)

When a SLEEP instruction is executed in high-speed mode a transition is made to

watch mode or subactive mode*

When a SLEEP instruction is executed in subactive mode, a transition is made to

subsleep mode or watch mode

After watch mode is cleared, a transition is made to subactive mode

Note:

When a transition is made to watch mode or subactive mode, high-speed mode must

be set.
