Hardware Functional Specification
Issue Date: 2005/12/13
CNF[4:0], A[15:1], A0, D[7:0], RD#, WR#, AS and CS are used as control signals for the
microprocessor data bus. A0 is normally connected to the lowest bit of the system address
bus. CNF[4:2] change the operation of the RD# and WR# pins to enable interfacing to
either a Generic (Z80), M6800, or MC68K family bus, and should be pulled-up or pulled-
down according to Table 5-6: “Summary of Configuration Options,” on page 20.
The following table shows the signal states for each function.
