23B.11 Direct Transitions (U-Mask, W-Mask Version, H8S/2635 Group
Only)
23B.11.1 Overview of Direct Transitions
There are three modes, high-speed, medium-speed, and subactive, in which the CPU executes
programs. When a direct transition is made, there is no interruption of program execution when
shifting between high-speed and subactive modes. Direct transitions are enabled by setting the
LPWRCR DTON bit to 1, then executing the SLEEP instruction. After a transition, direct
transition interrupt exception processing starts.
(1) Direct Transitions from High-Speed Mode to Subactive Mode
Execute the SLEEP instruction in high-speed mode when the SBYCR SSBY bit = 1, LPWRCR
LSON bit = 1, and DTON bit = 1, and TSCR (WDT1) PSS bit = 1 to make a transition to
subactive mode.
(2) Direct Transitions from Subactive Mode to High-Speed Mode
Execute the SLEEP instruction in subactive mode when the SBYCR SSBY bit = 1, LPWRCR
LSON bit = 0, and DTON bit = 1, and TSCR (WDT1) PSS bit = 1 to make a direct transition to
high-speed mode after the time set in SBYCR STS2 to STS0 has elapsed.
