This active low output indicates
that a data bus transfer is complete. A 10 k
pull-up resistor is required at this
output.

STi0-5
ST-BUS Inputs 0 to 5
(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.

STi6/A6
ST-BUS Input 6/Addr.6 input
(Input). The function of this pin is determined 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 multiplexed
CPU bus (44 pin only) 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 2.048 Mb/s to 4.196 or 8.192 Mb/s) the A6 input should be
connected to pin STo6/A6.

STi7/A7
ST-BUS Input 7/Addr.7 input
(Input): The function of this pin is determined 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 multiplexed CPU bus
(44 pin only) 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.

Frame Pulse
(Input). This input accepts and automatically identifies frame
synchronization signals formatted according to ST-BUS and GCI interface
specifications.

CLK
Clock
(Input). Serial clock for shifting data in/out on the serial streams.
Depending on the serial interface speed selected by IMS (Interface Mode Select)
register, the clock at this pin can be 4.096 or 8.192 MHz.

A0-2/
STi8-10
Address 0-2 / Input Streams 8-10
(Input). When non-multiplexed CPU bus is
selected, these lines provide the A0-A2 address lines to MT8986 internal
registers. When 16x8 switching configuration is selected (in 44 pin only), then
these pins are ST-BUS serial inputs 8 to 10 receiving data at 2.048 Mb/s.

13-15
A3-5/
STi11-13
Address 3-5 / Input Streams 11-13
(Input). When non-multiplexed CPU bus is
selected, these lines provide the A3-A5 address lines to MT8986 internal
registers. When 16x8 switching configuration is selected (in 44 pin only), then
these pins are ST-BUS serial inputs 11 to 13 receiving data at 2.048 Mb/s.
