Serial Output Streams 0 to 15 (5 V-Tolerant Slew-Rate-Limited
Three-state I/Os with Enabled Internal Pull-downs)
The data rate of all the output streams are programmed through
the “Data Rate Selection Register” on page 31. In the 2.048 Mbps
mode, these pins output serial TDM data streams at 2.048 Mbps
with 32 channels per frame. In the 4.096 Mbps mode, these pins
output serial TDM data streams at 4.096 Mbps with 64 channels
per frame. In the 8.192 Mbps mode, these pins output serial TDM
data streams at 8.192 Mbps with 128 channels per frame. In the
16.384 Mbps mode, these pins output serial TDM data streams at
16.384 Mbps with 256 channels per frame.These output streams
can be used as bi-directionals by programming BDL (bit 6) of
Internal Mode Selection (IMS) register.
Output Drive Enable (5 V-Tolerant Input with Internal Pull-up)
This is the output enable control for STio0 - 15. When it is high,
STio0 - 15 are enabled. When it is low, STio0 - 15 are tristated.
Data Bus 0 to 15 (5 V-Tolerant Slew-Rate-Limited Three-state
I/Os)
These pins form the 16-bit data bus of the microprocessor port.
Data Transfer Acknowledgment_Ready (5 V-Tolerant
Three-state Output)
This active low output indicates that a data bus transfer is
complete for the Motorola interface. For the Intel interface, it
indicates a transfer is completed when this pin goes from low to
high. An external pull-up resistor MUST hold this pin at HIGH level
for the Motorola mode. An external pull-down resistor MUST hold
this pin at LOW level for the Intel mode.
Chip Select (5 V-Tolerant Input)
Active low input used by the Motorola or Intel microprocessor to
enable the microprocessor port access.
Read/Write_Write (5 V-Tolerant Input)
This input controls the direction of the data bus lines (D0 - 15)
during a microprocessor access. For the Motorola interface, this
pin is set high and low for the read and write access respectively.
For the Intel interface, a write access is indicated when this pin
goes low.
Data Strobe_Read (5 V-Tolerant Input)
This active low input works in conjunction with CS to enable the
microprocessor port read and write operations for the Motorola
interface. A read access is indicated when it goes low for the Intel
interface.
