ST72C334屬于集成電路（IC）的微控制器。由意法半導(dǎo)體集團制造生產(chǎn)的ST72C334微控制器微控制器產(chǎn)品是相對復(fù)雜的用戶可編程數(shù)字邏輯器件。這些產(chǎn)品與視為微控制器的器件密切相關(guān)，兩者之間的區(qū)別主要體現(xiàn)在制造商選擇的用詞。不過按照傳統(tǒng)，微控制器集成了工作存儲器，也更可能包含混合信號外設(shè)，并且往往與更簡單的軟件范例結(jié)合使用，旨在重復(fù)執(zhí)行一系列預(yù)定義的任務(wù)。

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 .
