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 from active mode to active mode changes the operating
frequency. 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.
Notes: 1. To make a transition to another mode by an interrupt, make sure interrupt handling is after the interrupt
