0 When a SLEEP instruction is executed in active mode, a transition is
1
made to standby mode, watch mode, or sleep mode.
When a SLEEP instruction is executed in subactive mode, a transition is
made to watch mode or subsleep mode.
When a SLEEP instruction is executed in active (high-speed) mode, a direct
transition is made to active (medium-speed) mode if SSBY = 0, MSON = 1, and
LSON = 0, or to subactive mode if SSBY = 1, TMA3 = 1, and LSON = 1.
When a SLEEP instruction is executed in active (medium-speed) mode, a direct
transition is made to active (high-speed) mode if SSBY = 0, MSON = 0, and
LSON = 0, or to subactive mode if SSBY = 1, TMA3 = 1, and LSON = 1.
When a SLEEP instruction is executed in subactive mode, a direct
transition is made to active (high-speed) mode if SSBY = 1, TMA3 = 1, LSON = 0,
and MSON = 0, or to active (medium-speed) mode if SSBY = 1, TMA3 = 1,
LSON = 0, and MSON = 1.
Medium speed on flag
0 Operates in active (high-speed) mode
1 Operates in active (medium-speed) mode
