Low-Power Modes
STOP Mode
PS022825-0908
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
functions 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 Brownout 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 on Stop Mode
Recovery, see

Primary crystal oscillator and internal precision oscillator are stopped; XIN and
XOUT (if previously enabled) are disabled, and PA0/PA1 revert to the states
programmed by the GPIO registers.
System clock is stopped.
eZ8 CPU is stopped.
Program counter (PC) stops incrementing.
Watchdog Timer’s internal RC oscillator continues to operate if enabled by the
Oscillator Control register.
If enabled, the Watchdog Timer logic continues to operate.
If enabled for operation in STOP mode by the associated Flash Option Bit, the
Voltage Brownout protection circuit continues to operate.
Low-power operational amplifier continues to operate if enabled by the Power
Control register to do so.
All other on-chip peripherals are idle.
