POWER SAVING MODES
(Cont’d)
9.3 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’ instruction.
All peripherals remain active. During WAIT mode,
the I bit of the CC register is cleared, to enable all
interrupts. All other registers and memory remain
unchanged. The MCU remains in WAIT mode until
an interrupt or RESET occurs, whereupon the Pro-
gram Counter branches 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 22

Figure 22. WAIT Mode Flow-chart
Note:
1.
Before servicing an interrupt, the CC register is
pushed on the stack. The I bit of the CC register is
set during the interrupt routine and cleared when
the CC register is popped.
