OVERVIEW
The ST7 real-time development tools consist of various hardware and software components, which together form a flexible and sophisticated system designed to provide comprehensive development support for the ST7 family of MCUs.
The Hardware Development System (HDS) mainframe is common to all ST7 devices and, in conjunction with various active probes, allows emulation and development of specific devices. Only the probe needs to be changed to emulate a new ST7 family device.

FEATURES
■ A common Hardware Development System mainframe supports the entire ST7 family of MCUs, in conjunction with the appropriate ST7xxx-DBE Active Probe.
■ Real-time source level emulation allows viewing and breakpoint setting on high level source code rather than on disassembled target code for optimum user friendliness.
■ 64 KBytes of user modifiable and configurable emulation RAM, allows memory mapping of all ST7 family devices as well as modelling hypothetical memory configurations.
■ Unlimited breakpoints may be set for any opcode fetch or any address access, and conditions may be defined for the generation of 2 external synchronization signals.
■ 1K by 32-bit wide trace memory allows complex and sequential events to be defined on any combination of address and data, as well as 3 internal and 5 external logic signals.
■ User defined events may trigger a breakpoint or simply define data capture parameters, in accordance with user preferences.
■ Simple connection of the emulator system to the Host PC via parallel port.
■ Emulation system may be driven by a Windowsbased GNU debugger software or DOS software running on host PC, allowing full control and monitoring of hardware resources.
■ Multiple windows allow concurrent real-time display of source code, MCU resources, internal registers, trace data, etc.
■ Log files allow storage and subsequent redisplay of any displayed screen for subsequent analysis.
■ Command files can be used to execute a set of debugger commands in batch mode.
■ Editable configuration files ensure tailoring of working environment to user preferences.
■ Special Function Register window - symbolic display of SFR .
