Bit 3 Direct Transfer on Flag (DTON): This bit designates whether or not to make direct
transitions among active (high-speed), active (medium-speed) and subactive mode when a SLEEP
instruction is executed. The mode to which the transition is made after the SLEEP instruction is
executed depends on a combination of this and other control bits.
Bit 3: DTON

Bit 2 Medium Speed on Flag (MSON): After standby, watch, or sleep mode is cleared, this bit
selects active (high-speed), active (medium-speed), or sleep (medium-speed) mode.
Bit 2: MSON

Description
Description
When a SLEEP instruction is executed in active mode, a transition is 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
After standby, watch, or sleep mode is cleared, operation is in active (high-
speed) mode
When a SLEEP instruction is executed in active mode, a transition is made
to sleep (high-speed) mode
After standby, watch, or sleep mode is cleared, operation is in active
(medium-speed) mode
When a SLEEP instruction is executed in active mode, a transition is made
to sleep (medium-speed) mode
