Micro IN-system Programmer Brief Installation Notes
Enter the src directory.
If uisp does not compile successfully, add switch -DNO_DIRECT_IO in the
Makefile to remove support for direct I/O port access (that may be
necessary on non-PC architectures). Parallel port access should still
work if you have the Linux ppdev driver (patch for 2.2.17 is in the
kernel directory, ppdev is standard in 2.4 kernels). Please lobby
Alan Cox to include this tiny little driver in 2.2.x too :).
To make it type:
make
and to install it:
make install
If you have any further doubts, please consult UISP s homepage:

The ISD51_Demo project for the MSC1200 shows how to use the ISD51
IN-system-Debugger with flash breakpoints or hardware breakpoints.
By default, it is configured for flash breakpoints which allow you
to set real-time breakpoints in your software. Using Flash breakpoints
has also the benefit that no special handing for the shared interrupt
vector is required, since the hardware break registers of the MSC1200
are not used at all.
The W78E58B is an 8-bit microcontroller which has an IN-system programmable Flash EPROM for
firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The
W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the
contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary
ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4-
bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight
sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the
W78E58B allows the program memory to be programmed and read electronically. Once the code is
confirmed, the user can protect the code for security
