POWER SAVING MODES (Cont’d)
9.4 ACTIVE-HALT AND HALT MODES
ACTIVE-HALT and HALT modes are the two low-
est power consumption modes of the MCU. They
are both entered by executing the ‘HALT’ instruc-
tion. The decision to enter either in ACTIVE-HALT
or HALT mode is given by the LTCSR/ATCSR reg-
ister status as shown in the following table:
9.4.1 ACTIVE-HALT Mode
ACTIVE-HALT mode is the lowest power con-
sumption mode of the MCU with a real time clock
available. It is entered by executing the ‘HALT’ in-
struction when active halt mode is enabled.
The MCU can exit ACTIVE-HALT mode on recep-
tion of a Lite Timer / AT Timer interrupt or a RE-
SET.
– When exiting ACTIVE-HALT mode by means of
a RESET, a 256 CPU cycle delay occurs. After
the start up delay, the CPU resumes operation
by fetching the reset vector which woke it up (see
– When exiting ACTIVE-HALT mode by means of
an interrupt, the CPU immediately resumes oper-
ation by servicing the interrupt vector which woke
it up (see Figure 20).
When entering ACTIVE-HALT mode, the I bit in
the CC register is cleared to enable interrupts.
Therefore, if an interrupt is pending, the MCU
wakes up immediately.
In ACTIVE-HALT mode, only the main oscillator
and the selected timer counter (LT/AT) are running
to keep a wake-up time base. All other peripherals
are not clocked except those which get their clock
supply from another clock generator (such as ex-
ternal or auxiliary oscillator).
Caution: As soon as ACTIVE-HALT is enabled,
executing a HALT instruction while the Watchdog
is active does not generate a RESET if the
WDGHALT bit is reset.
This means that the device cannot spend more
than a defined delay in this power saving mode.

Figure 20. ACTIVE-HALT Mode Flowchart
Notes:
1. This delay occurs only if the MCU exits ACTIVE-
HALT mode by means of a RESET.
2. Peripherals clocked with an external clock
source can still be active.
3. Only the Lite Timer RTC and AT Timer interrupts
can exit the MCU from ACTIVE-HALT mode.
4. 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.
