COMPLEMENTARY ADDRESS AND DATA
In some user prototype instruments, data and address information may be the complement
of the data and address information on the buses of the µProcessor Lab. In this situation,
the data and/or address from the µProcessor Lab must be complemented before being
programmed into the PROM.
1702A Complementary Address And Data
Removing jumper J 1 and installing jumper J2 complements the address. To program
compiementary data into the PROM, jun1per J3 must be installed and jumper J4 removed.
See Fig. 9-2 for jumper locations. Data information may also be complemented by a
software command. See 8001/8002 µProcessor Lab System User's Manual.
