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.
Output Drive Enable (5 V-Tolerant Input with Internal Pull-up)
This is the output enable control for STio0 - 31 and the
output-driven-high control for STOHZ0 - 15. When it is high, STio0
- 31 and STOHZ0 - 15 are enabled. When it is low, STio0 - 31 are
tristated and STOHZ0 - 15 are driven high.
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.
