Low-Power Modes
PS025113-1212
STOP Mode
The Z8 Encore! F0830 Series products contain power saving features. The highest level of
power reduction is provided by the STOP Mode. The next level of power reduction is pro-
vided by the HALT Mode.
Further power savings can be implemented by disabling the individual peripheral blocks
while in NORMAL Mode.
The user must not enable the pull-up register bits for unused GPIO pins, since these ports
are default output to VSS. Unused GPIOs include those missing on 20-pin packages, as
well as those missing on the ADC-enabled 28-pin packages.
Executing the eZ8 CPU’s STOP instruction places the device into STOP Mode. In STOP
Mode, the operating characteristics are:
•

To minimize the current in STOP Mode, all GPIO pins that are configured as digital inputs
must be driven to V
