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.
