7.3 STOP MODE
STOP mode is the lowest power consumption
mode of the MCU (see
The MCU goes into STOP mode as soon as the
STOP instruction is executed. This has the follow-
ing effects:
– Program execution is stopped, the microcontrol-
– The contents of RAM and the peripheral regis-
– The oscillator is stopped, so peripherals cannot
Exit from STOP Mode
The MCU remains in STOP mode until one of the
following events occurs:
– RESET (Watchdog, LVD or RESET pin)
– A peripheral interrupt (assuming this peripheral
– An external interrupt (I/O port, NMI)
In all cases a delay of 2048 clock cycles (f

voltage is higher than the RAM retention voltage.

The Program Counter then points to the starting

(see
STOP Mode and Watchdog
When the Watchdog is active (hardware or soft-
ware activation), the STOP instruction is disabled
and a WAIT instruction will be executed in its place
unless the EXCTNL option bit is set to 1 in the op-
tion bytes and a a high level is present on the NMI
pin. In this case, the STOP instruction will be exe-
cuted and the Watchdog will be frozen.
