User Manual

The Z8051 OCD In-System Programmer

The Z8051 On-Chip Debugger (OCD) In-System Programmer (ISP) has been developed

to support Zilog’s Z8051 8-bit MCUs. This document describes how to set up and use the

Z8051 On-Chip Debugger ISP with your Z8051 Development Kit. The OCD ISP is used

to program the Flash or EEPROM memory spaces of a target Z8051 MCU using Zilog’s

On-Chip Debugger. The OCD interface uses only two I/O lines

and does not require a

socket adapter or specified power circuit. An example ISP screen is shown in Figure 74.

If your system V

is lower than device specifications, the OCD cannot program the

device.

1. The Z8051 OCD ISP requires a two-connection pin in your target system.
