HT-ICE is Holtek's early simulator. At present, only a few MCUs use HT-ICE as a development tool. Holtek’s new MCU products use e-Link as a debug tool.
HT-ICE uses LPT interface, but few devices have LPT interface. This product is an USB cable for HT-ICE. One end is an USB connector, and the other end is an LPT connector. Users can connect HT-ICE to the computer's USB port through this cable.
