Description

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 (1 K typical) is required at

this output.

18, 19, 20, D0 - D3, Data Bus D0 - D7 (Bidirectional). These pins form the 8-

21, D4 - D7 bit bidirectional data bus of the microprocessor port.

A0 - Address A0 to A10 (Input). These inputs provide the A10

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.
