Data Acknowledgment (Open Drain Output). This active low output indicates that a
data bus transfer is complete. A pull-up resistor is required at this output.
ST-BUS Inputs 0 to 5 (5V-tolerant Inputs). Serial data input streams. These streams
may have data rates of 2.048, 4.096 or 8.192 Mbit/s with 32, 64 or 128 channels,
respectively.
by the switching configuration enabled. If non-multiplexed CPU bus is used along with
a higher input rate of 8.192 or 4.096 Mb/s, this pin provides A6 address input function.
For 2.048 and 4.096 Mb/s (8x4) applications or when the multiplexed CPU bus
interface is selected, this pin assumes STi6 function. See Control Register bits
description and Tables 1, 2, 6 & 7 for more details.
Note that for applications where both A6 and STi6 inputs are required simultaneously
(e.g., 8 x 4 switching configuration at 4.096 Mb/s or rate conversion between 2.048Mb/
s to 4.196 or 8.192 Mb/s) the A6 input should be connected to pin STo6/A6.
by the switching configuration enabled. If non-multiplexed CPU bus is used along with
a higher input rate of 8.192 Mb/s, this pin provides A7 address input function.
For 2.048 and 4.096 Mb/s (8x4) applications or when the multiplexed CPU bus is
selected, this pin assumes STi7 function. See Control Register bits description and
Tables 1, 2, 6 & 7 for more details.
Note that for applications where both A7 and STi7 inputs are required simultaneously
(e.g., 2.048 to 8.192 Mb/s rate conversion) the A7 input should be connected to pin
STo7/A7.
