MultiplexedMicroprocessorBusInterface
The MULT/INT pin is sampled on power-up and, if LOW, the microprocessor bus format is assumed to be Multiplexed and the
pin is considered an input pin to indicate Multiplexed bus format. The pin has an internal pull-up and thus if pin is left floating, it
will be considered as in Non-multiplexed mode. The interface consists of an eight bit multiplexed Address/Data microprocessor
bus (only the A0, A1, A2 and A3 address lines are decoded), and six control lines (CE, RST, AS/MI, RD/DS, WR/(R/W) and the
MULT input) which should be tied LOW.

I Read or Data Strobe. With an Intel mP this signal indicates
a Read operation (active low polarity signal) or with a
Motorola
m
P, a Data strobe (active high polarity signal).
AS/MI

I Multiplexed Bus input or INTerrupt output. It is internally
pulled HIGH to indicate a Non-Multiplexed bus format and
needs to be pulled LOW externally to indicate the
Multiplexed bus format.
Non-Multiplexed Microprocessor Interface
The MULT/INT pin is sampled on power-up and, if not LOW, the microprocessor bus format is assumed to be Non-multiplexed.
This interface consists of a four-bit Address bus, an eight-bit Data bus and six control lines (CE RST, AS/MI, RD/DS,
WR/(R/WR) and the INT signal if enabled).
