4. Time for direct transition from subactive mode to active (medium-speed) mode
A direct transition from subactive mode to active (medium-speed) mode is performed by
executing a SLEEP instruction in subactive mode while bit SSBY is set to 1 and bit LSON is
cleared to 0 in SYSCR1, bits MSON and DTON are both set to 1 in SYSCR2, and bit TMA3 is set
to 1 in TMA. The time from execution of the SLEEP instruction to the end of interrupt exception
handling (the direct transition time) is given by equation (4) below.
Direct transition time = { (Number of SLEEP instruction execution states) + (number of internal
Example: Direct transition time = (2 + 1) 8t
