instruction execution to interrupt exception handling completion is calculated by expression (3)
below.
Time Required before Direct Transfer from Subactive Mode to Active (Medium-Speed)
Mode: A direct transfer is made 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 and DTON bits in SYSCR2 are set to 1, and the
TMA3 bit in TMA is set to 1. A direct transfer time, that is, the time from SLEEP instruction
execution to interrupt exception handling completion is calculated by expression (4) below.
Direct transfer time = (number of states for SLEEP instruction execution + number of
Example: Direct transfer time for the H8/3834 Series
Direct transfer time = (number of states for SLEEP instruction execution + number of
