Description
Direct Transfer On Flag
Specifies the operating mode to be entered after executing
the SLEEP instruction.
When the SLEEP instruction is executed in high-speed
mode or medium-speed mode:
0: Shifts to sleep mode, software standby mode, or watch
1: Shifts directly to subactive mode, or shifts to sleep mode
When the SLEEP instruction is executed in subactive
mode:
0: Shifts to subsleep mode or watch mode
1: Shifts directly to high-speed mode, or shifts to subsleep
Low-Speed On Flag
Specifies the operating mode to be entered after executing
the SLEEP instruction. This bit also controls whether to shift
to high-speed mode or subactive mode when watch mode
is cancelled.
When the SLEEP instruction is executed in high-speed
mode or medium-speed mode:
0: Shifts to sleep mode, software standby mode, or watch
1: Shifts to watch mode or subactive mode
When the SLEEP instruction is executed in subactive
mode:
0: Shifts directly to watch mode or high-speed mode
1: Shifts to subsleep mode or watch mode
When watch mode is cancelled:
0: Shifts to high-speed mode
1: Shifts to subactive mode
