The MAXQ Parallel Port to JTAG Interface target interface provides access to MAXQ target hardware via a MAXQ parallel port-to-JTAG interface. This target interface supports program loading and debugging. When debugging with this target interface you will have access to four program breakpoints and two data breakpoints. Note that one of the program breakpoints will be needed for single stepping and one of the data breakpoints will be needed for the debug io library.
