Microprocessor Interface and Registers
The MUSAC is programmed via the
μ
P interface. It consists of the address data bus AD7 … AD0,
the address bits A1 … A0, the Write (WR), the Read (RD), the Address Latch Enable (ALE), the
Interrupt (INT) and the Chip Select (CS) signal, as shown in
figure 15
.

Controlled by a Intel Microprocessor
The standard 8-bit
μ
P interface can communicate with Intel multiplexed/demultiplexed
microprocessors as well as with Motorola demultiplexed processors. It gives access to the internal
registers and to the control memories (Connection Memory, Conference Control Memory).
