PS: Power Saving
The AT91M40400 Power Saving module provides a low-
power Idle Mode. In Idle Mode, the CPU clock is deacti-
vated while all on-chip peripherals and the RAM remain
active. The contents of the on-chip RAM and all the special
function registers remain unchanged during this mode. The
Idle Mode can be terminated by any enabled interrupt or by
a hardware Reset.
