the mixture of noise. Should noise be mixed in, insert a capacitor between the CNF2 and

Tristate input/output, active high
These pins comprise an 8-bit bidirectional data bus, which is connected to the 8-bit or 16-bit MPU data bus.
Input, active high
The S1D13700 allows the MPU interface format to be changed depending on how CNF2 and CNF3 are set,
so that it can be connected directly to the 80-series MPU (e.g., Z80
or 6802), or the MC68K-series MPU (68000) bus.
Input, active high
Normally, the MPU address bus is connected to these pins. The data bus signal is discriminated by a combi-
nation of RD# and WR# signals, or R/W#, E, and LDS signals, as listed in the table below.
Input: CNF4 = 0 selects direct access; CNF4 = 1 selects indirect access.
<Direct access for the 80-series interface>
<Indirect access for the 80-series interface>
Settings marked with * are inhibited.
*AB15–AB0 are used as register addresses.
