HALT Mode
Peripheral-Level Power Control
Power Control Register Definitions
Executing the eZ8 CPU’s HALT instruction places the device into HALT Mode, which
powers down the CPU but leaves all other peripherals active. In HALT Mode, the operat-
ing characteristics are:
•
•
•
•
•
•
•
The eZ8 CPU can be brought out of HALT Mode by any of the following operations:
•
•
•
•
•
To minimize current in HALT Mode, all GPIO pins that are configured as inputs must be
driven to one of the supply rails (V
In addition to the STOP and HALT modes, it is possible to disable each peripheral on each
of the Z8 Encore! XP F082A Series devices. Disabling a given peripheral minimizes its
power consumption.
The following sections define the Power Control registers.
Power Control Register 0
Each bit of the following registers disables a peripheral block, either by gating its system
clock input or by removing power from the block. The default state of the low-power
