31 / 158 page  ST72589BW, ST72389BW 31/158 POWER SAVING MODES (Cont’d) 4.2.3 WAIT Mode WAIT mode places the MCU in a low power con- sumption mode by stopping the CPU. This power saving mode is selected by calling the “WFI” ST7 software instruction. All peripherals remain active. During WAIT mode, the I1 and I0 bits of the CC register are forced to level 0 (“10”), to enable all interrupts. All other reg- isters and memory remain unchanged. The MCU remains in WAIT mode until an interrupt or Reset occurs, whereupon the Program Counter branch- es to the starting address of the interrupt or Reset service routine. The MCU will remain in WAIT mode until a Reset or an Interrupt occurs, causing it to wake up. Refer to Figure 20. Figure 20.
