No connection. These pins must be left open for normal
operation.
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 (1 K typical) is required at this output.
Data Strobe (Input). This active low input works in conjunction
with CS to enable the read and write operations.
Chip Select (Input). This active low input is used by a
microprocessor to activate the microprocessor port.
Read/Write (Input). This input controls the direction of the data
bus lines (D7-D0) during a microprocessor access.
Data Transfer Acknowledgment (Open Drain Output). This
active low output indicates that a data bus transfer is completed.
A pull-up resistor (1 K typical) is required at this output.
Data Bus D0 - D7 (Bidirectional). These pins form the 8 bit
bidirectional data bus of the microprocessor port.
Address A0 to A10 (Input). These inputs provide the A10 - A0
address lines to the internal registers.
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.
Send PCM Signal Output (Output). Port 1
TDM data output streams. Sout pin outputs serial TDM data
streams at 2.048 Mbps with 16 channels per stream.
Receive PCM Signal Output (Output). Port 2 TDM data output
streams. Rout pin outputs serial TDM data streams at
2.048 Mbps with 16 channels per stream.
Send PCM Signal Input (Input). Port 2 TDM data input streams.
Sin pin receives serial TDM data streams at 2.048 Mbps with 16
channels per stream.
