DESCRIPTION
The ST20-JPI parallel port to JTAG interface is
a host interface to allow connection from a PC
parallel port to any JTAG diagnostic controller
based ST20 development board. The interface
plugs into any standard PC 25 way D-type
parallel port. Supported parallel port modes
are:
• Nibble mode
• Byte mode
• EPP mode
depending on which mode the host PC can
support. Connection to the development target
is via a 20 way IDC JTAG connector. Once
connected, the development target can be
accessed using the MS Windows drivers
supplied with the standard ST20 toolset.
