ZBasic System Library

ZBasic Microcontrollers
The various ZBasic target devices offer a variety of resources for use in your program, e.g. timers,
interrupts, UART (hardware serial port), analog-to-digital converters, etc. Some of these resources are
allocated to specific functions of ZBasic and/or are used by certain ZBasic System Library routines. The
resources available on a particular target device vary and the remainder of this section documents the
availability for each supported device. Consult the datasheet for the particular target device for detailed
information about the device.
In some of the following sub-sections, resource usage is described separately for ZX devices and generic
target devices. In others, resource usage is described only in terms of the base device and it is thus
necessary to know the base device underlying your particular ZX device; the table below shows the
correspondence.

In the following sub-sections, some of the tables include package designation codes for the different
processor types because the pin assignments vary by package type. The table below gives package
designation codes and the corresponding package types for various devices. Note, particularly, that
suffixes like A, P and PA have been omitted because the package availability is generally the same
irrespective of the suffix.
