Section 6 Power-Down Modes
6.2
Figure 6.1 shows the possible transitions among these operating modes. A transition is made from
the program execution state to the program halt state by executing a SLEEP instruction. Interrupts
allow for returning from the program halt state to the program execution state. A direct transition
between active mode and subactive mode, which are both program execution states, can be made
without halting the program. The operating frequency can also be changed in the same modes by
making a transition directly from active mode to active mode, and from subactive mode to
subactive mode. RES input enables transitions from a mode to the reset state. Table 6.2 shows the
transition conditions of each mode after the SLEEP instruction is executed and a mode to return
by an interrupt. Table 6.3 shows the internal states of the LSI in each mode.
