1 Holtek 8051 e-Link Driver Instructions and Installation
The Holtek 8051 e-Link driver is an AGDI interface debug adapter driver program which can be
embedded into an integrated development environment which supports an AGDI interface. It can be
used to assist users with rapid development of their application programs for Holtek’s 8051 series
MCUs.
The HT8051OCDS-ICE is composed of an e-Link, for the HT8051OCDS, and a target board
(with EV). The e-Link is a Holtek new generation OCDS structure in-circuit debug adapter which
provides customers with a development tool to directly debug their application boards. An OCDS
interfaced MCU is required on the application board.
As for the software, an integrated develop environment supporting the AGDI interface is necessary,
such as the KeilTM μVision, to develop the Holtek’s 8051 series MCU programs.
This user manual describes the way to use the e-Link Driver and the Holtek Database in the KeilTM
μVision environment as well as any relevant details regarding the HT8051OCDS-ICE.

HT8051OCDS-ICE Composition
▀ The HT8051OCDS-ICE is composed of two parts:
HT8051OCDS e-Link + Target Board (with EV) .
▀HT8051OCDS e-Link:
The e-Link is a Holtek new generation OCDS structure on-line debug adapter. When used with
the AGDI interfaced program development software, users are provided with a development tool
to directly debug their application boards.
▀e-Link Hardware Box:
e-Link (Front)
e-Link (Back)
e-Link (Side)
▀ Target Board (with EV):
The EV is an IC with an OCDS interface.
During debug, the e-Link can execute a range of debug operations such as single step, full speed,
halt and breakpoint setup by transmitting instructions to the EV. When it is not being used for
debug purposes, the EV will function in the same way as an actual IC.
