Chip Select:
A low level selects the MUSAC-A for
a register access operation.
Supply Voltage:
5 V
±
5 %
Read:
This signal indicates a read operation and is
internally sampled only if CS is active. The
MUSAC-A puts data from the selected internal reg-
ister on the data bus with the falling edge of RD.
RD is active low (Siemens/Intel 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-A loads an internal regis-
ter with data from the data bus at the rising edge of
WR. WR is active low (Siemens/Intel bus mode).
Address Latch Enable:
In the Intel type multi-
plexed
μ
P-interface mode a logical high on this line indi-
cates an address of a MUSAC-A internal register
on the external address/data bus. In the Intel type
demultiplexed.
μ
P-interface mode this line is hardwired to
V
SS
, in
the demultiplexed Motorola type
μ
P-interface
mode it should be connected to
V
DD
.
If ALE is not connected it will be set to ground inter-
nally.
Address Data Bus:
If the multiplexed
address/data
μ
P-interface bus mode is selected
these pins transfer data and addresses between
the
μ
P and the MUSAC-A.
