5.3
The CPU can execute programs in two modes: active and subactive modes. A direct transition is
made between these two modes without stopping program execution. A direct transition can also
be made when the operating clock is changed in active and subactive modes. The transition is
made via the sleep or watch mode, by setting the DTON bit in SYSCR2 to 1 to execute a SLEEP
instruction. After the mode transition, direct transition interrupt exception handling starts.
Note that if a direct transition is attempted while the I bit in CCR is 1, the transition is made to the
sleep or watch mode, though not returning from the mode.
5.3.1
When a SLEEP instruction is executed in active (high-speed) mode while the SSBY and LSON
bits in SYSCR1 are cleared to 0 and the MSON and DTON bits in SYSCR2 are set to 1, a
transition is made to active (medium-speed) mode via sleep 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 (1).
Direct transition time = {(Number of SLEEP instruction execution states) + (Number of internal
Example:
Direct transition time = (2 + 1) × 1tosc + 14 × 8tosc = 115tosc
