PRELIMINARY

Peripherals

The following sections describe the differences, changes, or limitations placed on any of the Z8FS040

peripherals or other functions from the base Z8F082A device. For more information on the operation

of each peripheral please refer to the appropriate section of PS0228.

Peripheral Availability

Table 4 - Peripheral Availability shows how the peripherals are used by Zilog’s PIR technology and

the differences from the base Z8F082A device. The peripherals used by the PIR technology should

not be used by the application unless the engine is disabled through the PIR Engine Enable register.
