ST-BUS Frame Pulse Output 2 (5V Tolerant High Speed
Three-state Output): ST-BUS frame pulse output which stays
low for 30 ns or 61 ns at the frame boundary. Its frequency is
8 KHz. The polarity of this signal can be changed using the
Internal Mode Selection register.
ST-BUS Clock Output 2 (5 V Tolerant High Speed Three-
state Output): A 32.768 MHz or 16.384 MHz clock output. The
clock falling edge defines the output frame boundary. The
polarity of this signal can be changed using the Internal Mode
Selection register.
Output Drive Enable (5 V Tolerant Input): This is the
asynchronously output enable control for the STo0 - 15 and the
output driven high control for the STOHZ 0 - 15 serial outputs.
When it is high, the STo0 - 15 and STOHZ 0 - 15 are enabled.
When it is low, the STo0 - 15 are in the high impedance state
and the STOHZ 0 - 15 are driven high.
Serial Output Streams 0 to 15 (5 V Tolerant Three-state
Outputs): The data rate of these output streams can be
selected independently using the stream control output
registers. In the 2.048 Mb/s mode, these pins have serial TDM
data streams at 2.048 Mb/s with 32 channels per stream. In the
4.096 Mb/s mode, these pins have serial TDM data streams at
4.096 Mb/s with 64 channels per stream. In the 8.192 Mb/s
mode, these pins have serial TDM data streams at 8.192 Mb/s
with 128 channels per stream.
Serial Output Streams High Impedance Control 0 to 15 (5 V
Tolerant Three-state Outputs): These pins are used to enable
(or disable) external three-state buffers. When a output channel
is in the high impedance state, the STOHZ drives high for the
duration of the corresponding output channel. When the STo
channel is active, the STOHZ drives low for the duration of the
corresponding output channel.
Data Bus 0 - 15 (5 V Tolerant I/Os): These pins form the 16-bit
data bus of the microprocessor port.
Data Transfer Acknowledgment (5 V Tolerant Three-state
Output): This active low output indicates that a data bus
transfer is complete. A pull-up resistor is required to hold this
pin at HIGH level.
Chip Select (5 V Tolerant Input): Active low input used by the
microprocessor to enable the microprocessor port access.
