Low-Power Modes
Overview
STOP Mode
PS025011-1010
The Z8 Encore! XP F1680 Series products have power-saving features. The highest level
of power reduction is provided by the STOP mode. The next lower level of power 
reduction is provided by the HALT mode.
Further power savings can be implemented by disabling individual peripheral blocks
while in NORMAL mode.
Executing the eZ8 CPU’s Stop instruction places the device into STOP mode. 
In STOP mode, the operating characteristics are:
