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
1
and does not require a
socket adapter or specified power circuit. An example ISP screen is shown in Figure 74.
If your system V
CC
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.
