STOP Mode
The Z8 Encore! XP F082A Series products contain power-saving features. The highest
level of power reduction is provided by the STOP Mode, in which nearly all device func-
tions are powered down. The next lower level of power reduction is provided by the
HALT Mode, in which the CPU is powered down.
Further power savings can be implemented by disabling individual peripheral blocks
while in Active mode (defined as being in neither STOP nor HALT Mode).
Executing the eZ8 CPU’s STOP instruction places the device into STOP Mode, powering
down all peripherals except the Voltage Brown-Out detector, the Low-power Operational
Amplifier and the Watchdog Timer. These three blocks may also be disabled for additional
power savings. Specifically, the operating characteristics are:
To minimize current in STOP Mode, all GPIO pins that are configured as digital inputs
must be driven to one of the supply rails (V
ured as outputs must also be driven to one of the supply rails. The device can be brought
out of STOP Mode using Stop Mode Recovery. For more information about Stop Mode
Recovery, see the
page 22.
