Power Control Register 0
Executing the eZ8 CPU HALT instruction places the device into HALT mode. In HALT
mode, the operating characteristics are:
•
•
•
•
•
•
•
The eZ8 CPU can be brought out of HALT mode by any one of the following operations:
•
•
•
•
•
To minimize current in HALT mode, all GPIO pins that are configured as digital inputs
must be driven to VDD when pull-up register bit is enabled or to one of power rail (VDD
or GND) when pull-up register bit is disabled.
In addition to the STOP and HALT modes, it is possible to disable each peripheral on each
of the Z8 Encore!
power consumption.
Each bit of the following registers disables a peripheral block, either by gating its system
clock input or by removing power from the block.
Primary oscillator is enabled and continues to operate.
System clock is enabled and continues to operate.
eZ8 CPU is stopped.
Program counter (PC) stops incrementing.
Watchdog Timer’s internal RC oscillator continues to operate.
If enabled, the Watchdog Timer continues to operate.
All other on-chip peripherals continue to operate.
