Low-Power Modes
PS024611-0408
Caution:
STOP Mode
HALT Mode
The Z8FMC16100 Series Flash MCU 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.
Executing eZ8 CPU’s STOP instruction places the Z8FMC16100 Series Flash MCU into
STOP mode. In STOP mode, the operating characteristics include:
•
•
•
•
•
•
•
•
To minimize current in STOP mode, all GPIO pins which are configured as digital inputs
must be driven to one of the supply rails (V
disabled. The device can be brought out of STOP mode using Stop Mode Recovery. For
more information, see
To prevent excess current consumption, STOP mode must not be used if the device is driven
with an external clock source.
Execution of the eZ8 CPU’s HALT instruction places the device into HALT mode. In
HALT mode, the operating characteristics are:
•
•
•
Primary crystal oscillator and IPO are stopped; XIN and XOUT pins are driven to V
System clock is stopped.
eZ8 CPU is stopped.
Program counter (PC) stops incrementing.
If enabled for operation during STOP mode, the WDT and its internal RC oscillator
continue to operate.
If enabled for operation in STOP mode through the associated Option Bit, the VBO
circuit continues to operate.
Comparators and voltage reference operate unless disabled.
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
