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 of the program by executing a SLEEP
instruction. Interrupts allow for returning from the program halt state to the program execution
state of the program. 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.
