NICE-52 In-Circuit Emulator

NICE-52 In-Circuit Emulators fully emulate Intel 80(C)31/32 and 8x(C)51/52 microcontrollers. The NICE-52 comes standard with 64K code memory and 64K data memory. To support the flexibility of the Intel 8xC51/31 architecture the NICE-52 emulates internal, external, or combined internal/external program memory and data memory configurations. The NICE-52 provides full access to all 4 I/O ports, all interrupts, all SFR, and all DATA and code memory spaces of Intel 8xC51/31 CPU. Any bit or byte address can easily be viewed and edited with the integrated E52 debugger.
The E52 debugger lets you take advantage of IntelÆs many software support vendors including 2500AD, Archimedes, Avocet, IAR, Keil, and others. The debugger inter-face is simple and straightforward. All common commands are displayed on the screen and are controlled by the keyboard function keys. When commands are high-lighted from pull down menuÆs a description of the command is displayed on the bottom of the screen for easy reference. The E52 debugger gives you complete control over the NICE-52 emulator and your target operation. Operations include single step, go slow, single step but execute subroutine calls in real time, go in real time until a breakpoint is reached, and run in real time. Status windows show the program flow, SFR registers, and the internal and external data memory spaces.
There is also a watch window available to monitor C level variables in a user specified format (including support for local variables). Up to 10 breakpoints can be specified. Breakpoint conditions can include an address or address range in combination with the fetch, read, or write status and an external signal clip.
Debugging of Intel 8xC51/31 systems with the NICE-52 can be started almost right out of the box and mastered in minutes to make 8xC51/31 development simple and efficient.
