Low-Power Modes
STOP Mode
HALT Mode
PS022008-0810
Caution:
The ZNEO
Power management functions are divided into three categories to include CPU operating
modes, peripheral power control, and programmable option bits. The highest level of
power reduction is provided through a combination of all functions.
Execution of the ZNEO CPU’s
In 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
disabled, and WDT must be disabled. The device is brought out of STOP mode using Stop
Mode Recovery. For detailed information on Stop Mode Recovery, see
Mode Recovery
Execution of the ZNEO CPU’s
The following are the operating characteristics in HALT mode:
•
•
•
To prevent excess current consumption when using an external clock source in
IPO is stopped; XIN and XOUT pins are driven to V
System clock is stopped.
ZNEO 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
protection circuit continues to operate.
All other on-chip peripherals are non-active.
STOP Mode, the external clock must be disabled.
System clock is enabled and continues to operate.
ZNEO CPU is stopped.
PC stops incrementing.
