Serial Input Streams 0 to 31 (5 V-Tolerant Inputs with Enabled
Internal Pull-downs) The data rate of each input stream can be
selected independently using the Stream Input Control Registers
(SICR[n]). In the 2.048 Mbps mode, these pins accept serial TDM
data streams at 2.048 Mbps with 32 channels per frame. In the
4.096 Mbps mode, these pins accept serial TDM data streams at
4.096 Mbps with 64 channels per frame. In the 8.192 Mbps mode,
these pins accept serial TDM data streams at 8.192 Mbps with 128
channels per frame. In the 16.384 Mbps mode, these pins accept
TDM data streams at 16.384 Mbps with 256 channels per frame.
Serial Output Streams 0 to 31 (5 V-Tolerant Slew-Rate-Limited
Three-state I/Os with Enabled Internal Pull-downs) The data
rate of each output stream can be selected independently using
the Stream Output Control Registers (SOCR[n]). 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 BDH (bit 7) and BDL (bit 6) of Internal Mode
Selection (IMS) register.
Serial Output Streams High Impedance Control 0 to 15
(5 V-Tolerant Slew-Rate-Limited Three-state Outputs) These
pins are used to enable (or disable) external three-state buffers.
When an output channel is in the high impedance state, the
STOHZ drives high for the duration of the corresponding output
channel. When the STio channel is active, the STOHZ drives low
for the duration of the corresponding output channel. STOHZ
outputs are available for STio0 - 15 only.
