Z8 Encore!® Motor Control Flash MCUs

Product Specification

• System clock is enabled and continues to operate

• eZ8 CPU is stopped

• Program counter (PC) stops incrementing

• Watch-Dog Timer’s internal RC oscillator continues to operate

• If enabled, the Watch-Dog Timer continues to operate

• All other on-chip peripherals continue to operate

The eZ8 CPU can be brought out of HALT mode by any of the following operations:

• Interrupt or System Exception

• Watch-Dog Timer time-out (System Exception or reset)

• Power-on reset

• Voltage-brown out reset

• External RESET pin assertion

• Halt Mode Recovery time is less than 5µs.

To minimize current in HALT mode, all GPIO pins which are configured as inputs must be

driven to one of the supply rails (VCC or GND).

Peripheral-Level Power Control

In addition to the STOP and HALT modes, it is possible to disable unused on-chip analog

peripherals of the Z8FMC16100 Series Flash MCU device during operation. Disabling an

unused analog peripheral minimizes power consumption. Power consumption of the

unused on-chip digital peripherals is automatically minimized when not in use.
