5.3.4
When a SLEEP instruction is executed in active (medium-speed) mode while the SSBY, LSON,
and TMA3 bits in SYSCR1 are set to 1 and the DTON bit in SYSCR2 is set to 1, a transition is
made to subactive mode via watch mode.
The time from the start of SLEEP instruction execution to the end of interrupt exception handling
(the direct transition time) is calculated by equation (4).
Direct transition time = {(Number of SLEEP instruction execution states) + (Number of internal
5.3.5
When a SLEEP instruction is executed in subactive mode while the SSBY and TMA3 bits in
SYSCR1 are set to 1, the LSON bit in SYSCR1 is cleared to 0, the MSON bit in SYSCR2 is
cleared to 0, and the DTON bit in SYSCR2 is set to 1, a transition is made directly to active (high-
speed) mode via watch mode after the waiting time set in bits STS2 to STS0 in SYSCR1 has
elapsed.
The time from the start of SLEEP instruction execution to the end of interrupt exception handling
(the direct transition time) is calculated by equation (5).
Direct transition time = {(Number of SLEEP instruction execution states) + (Number of internal
Example:
Direct transition time = (2 + 1) × 8tosc + 14 × 8tw = 24tosc + 112tw

Example:
Direct transition time = (2 + 1) × 8tw + (8192 + 14) × 1tosc = 24tw + 8206tosc
