Section 5 Power-Down Modes
Direct transfer from subactive mode to active (medium-speed) 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.
