When a SLEEP instruction is executed in active (medium-speed) while the SSBY and LSON bits
in SYSCR1 are set to 1, the DTON bit in SYSCR2 is set to 1, and the TMA3 bit in TMA is set to
1, a transition is made to subactive mode via watch mode.
When a SLEEP instruction is executed in subactive mode while the SSBY bit in SYSCR1 is set to
1, the LSON bit in SYSCR1 is cleared to 0, the MSON bit in SYSCR2 is set to 1, the DTON bit in
SYSCR2 is set to 1, and the TMA3 bit in TMA is set to 1, a transition is made directly to active
(medium-speed) mode via watch mode after the waiting time set in SYSCR1 bits STS2 to STS0
has elapsed.

1. Time for direct transition from active (high-speed) mode to active (medium-speed) mode
A direct transition from active (high-speed) mode to active (medium-speed) mode is performed by
executing a SLEEP instruction in active (high-speed) mode while bits SSBY and LSON are both
cleared to 0 in SYSCR1, and bits MSON and DTON are both set to 1 in SYSCR2. The time from
execution of the SLEEP instruction to the end of interrupt exception handling (the direct transition
time) is given by equation (1) below.
Direct transition time = { (Number of SLEEP instruction execution states) + (number of internal
Example: Direct transition time = (2 + 1) 2t

2. Time for direct transition from active (medium-speed) mode to active (high-speed) mode
A direct transition from active (medium-speed) mode to active (high-speed) mode is performed by
executing a SLEEP instruction in active (medium-speed) mode while bits SSBY and LSON are
both cleared to 0 in SYSCR1, and bit MSON is cleared to 0 and bit DTON is set to 1 in SYSCR2.
