PS019921-0308
Caution:
The Z8 Encore! XP F64XX Series products contain power-saving features. The highest
level of power reduction is provided by STOP mode. The next level of power reduction is
provided by the HALT mode.
Execution of the eZ8
STOP mode, 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
must be disabled, and the Watchdog Timer must be disabled. The devices can be brought
out of STOP mode using Stop Mode Recovery. For more information on Stop Mode
Recovery, see
Execution of the eZ8 CPU’s HALT instruction places the device into HALT mode. In
HALT mode, the operating characteristics are:

devices with an external clock driver source.
STOP mode must not be used when driving the Z8 Encore! XP F64XX Series
Primary crystal oscillator is stopped; the XIN pin is driven High and the XOUT pin is
driven Low.
System clock is stopped.
eZ8 CPU is stopped.
Program counter (PC) stops incrementing.
The Watchdog Timer and its internal RC oscillator continue to operate, if enabled for
operation during STOP mode.
The Voltage Brownout protection circuit continues to operate, if enabled for operation
in STOP mode using the associated Option Bit.
All other on-chip peripherals are idle.
Primary crystal oscillator is enabled and continues to operate.
System clock is enabled and continues to operate.
eZ8 CPU is stopped.
