NC
No connection.
These pins must be left open for normal operation.
9
IRQ
Interrupt Request (Open Drain Output)
. This output goes low when an interrupt
occurs in any channel. IRQ returns high when all the interrupts have been read
from the Interrupt FIFO Register. A pull-up resistor (1K typical) is required at this
output.
10
DS
Data Strobe (Input)
. This active low input works in conjunction with CS to enable
the read and write operations.
11
CS
Chip Select (Input).
This active low input is used by a microprocessor to activate
the microprocessor port.
12
R/W
Read/Write (Input)
. This input controls the direction of the data bus lines (D7-D0)
during a microprocessor access.
13
DTA
Data Transfer Acknowledgment (Open Drain Output)
. This active low output
indicates that a data bus transfer is completed. A pull-up resistor (1K typical) is
required at this output.
18, 19, 20, 21,
23, 24, 25, 26
D0 - D3,
D4 - D7
Data Bus D0 - D7 (Bidirectional)
. These pins form the 8-bit bidirectional data bus
of the microprocessor port.
44, 45,46, 47,49,
50, 51,52,54, 55,
56
A0 - A10
Address A0 to A10 (Input)
. These inputs provide the A10 - A0 address lines to
the internal registers.
105
ODE
Output Drive Enable (Input).
This input pin is logically AND’d with the ODE bit-6
of the Main Control Register. When both ODE bit and ODE input pin are high, the
Rout and Sout ST-BUS outputs are enabled.
When the ODE bit is low or the ODE input pin is low, the Rout and Sout ST-BUS
outputs are high impedance.
106
Sout
Send PCM Signal Output (Output)
. Port 1 TDM data output streams.
Sout pin outputs serial TDM data streams at 2.048 Mb/s with 32 channels per
stream.
107
Rout
Receive PCM Signal Output (Output)
. Port 2 TDM data output streams. Rout pin
outputs serial TDM data streams at 2.048 Mb/s with 32 channels per stream.
109
Sin
Send PCM Signal Input (Input).
Port 2 TDM data input streams.
Sin pin receives serial TDM data streams at 2.048 Mb/s with 32 channels per
stream.
110
Rin
Receive PCM Signal Input (Input).
Port 1 TDM data input streams.
Rin pin receives serial TDM data streams at 2.048 Mb/s with 32 channels per
stream.
111
F0i
Frame Pulse (Input).
This input accepts and automatically identifies frame
synchronization signals formatted according to ST-BUS or GCI interface
specifications.
112
C4i
Serial Clock (Input).
4.096 MHz serial clock for shifting data in/out on the serial
streams (Rin, Sin, Rout, Sout).
