Power-down Modes
The sleep mode is a shut-down condition which is used to reduce the average system power
consumption in applications where the microcontroller is not fully utilized. In this mode, the sys-
tem clock is stopped. The sleep mode is entered via the SLEEP instruction. This instruction sets
the interrupt enable bit (I) in the condition code register to enable all interrupts and stops the
core. During the sleep mode the peripheral modules remain active and are able to generate
interrupts. The microcontroller exits the sleep mode by carrying out any interrupt or a reset.
The sleep mode can only be kept when none of the interrupt pending or active register bits are
set. The application of the $AUTOSLEEP routine ensures the correct function of the sleep
mode. For standard applications use the $AUTOSLEEP routine to enter the power-down mode.
Using the SLEEP instruction instead of the $AUTOSLEEP following an I/O instruction requires
the insertion of 3 non I/O instruction cycles (for example NOP NOP NOP) between the IN or
OUT command and the SLEEP command.
The total power consumption is directly proportional to the active time of the microcontroller. For
a rough estimation of the expected average system current consumption, the following formula
should be used:
I
DD depends on VDD and fsyscl
The ATAM893-D has various power-down modes. During the sleep mode the clock for the
MARC4 core is stopped. With the NSTOP bit in the clock management register (CM) it is pro-
grammable if the clock for the on-chip peripherals is active or stopped during the sleep mode. If
the clock for the core and the peripherals is stopped the selected oscillator is switched off. An
exception is the 32-kHz oscillator, if it is selected it runs continuously independent of the NSTOP
bit. If the oscillator is stopped or the 32-kHz oscillator is selected, power consumption is
extremely low.
