Input (I)
Function
Read: This signal indicates a read operation and is
internally sampled only if CS is active. The MUSAC puts
data from the selected internal register on the data bus
with the falling edge of RD. RD is active low (Siemens/
Intel bus mode).
Data Strobe: The rising edge marks the end of a valid
read or write operation (Motorola bus mode).
Write: This signal initiates a write operation. The WR
input is internally sampled only if CS is active. In this
case the MUSAC loads an internal register with data
from the data bus at the rising edge of WR. WR is active
low (Siemens/Intel bus mode).
Read/Write: When “high”, identifies a valid P access as
a read operation. When “low”, identifies a valid P
access as a write operation (Motorola bus mode).
Address Latch Enable: In the Intel type multiplexed P-
interface mode a logical high on this line indicates an
address of an MUSAC internal register on the external
address/data bus. In the Intel type demultiplexed P-
interface mode this line is hardwired to
demultiplexed Motorola type P-interface mode it should
be connected to
Address Data Bus: If the multiplexed address/data P-
interface bus mode is selected these pins transfer data
and addresses between the P and the MUSAC.
If a demultiplexed mode is used, these bits interface with
the system data bus.
PCM-Output Port: Serial data is sent by these lines at
standard CMOS- or TTL levels. These pins can be
tristated.
