DTA
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 Input 0 to 7 (Inputs).
Serial data input streams. These streams have 32
channels at data rates of 2.048 Mbit/s.

RESET
Device Reset (5v-tolerant input)
. This pin is only available for the 48-pin SSOP
package. This active low input puts the MT89L85 in its reset state. It clears the internal
counters anf registers. All ST-BUS outputs are set to the high impedance state. This
RESET pin must be held low for a minimum of 100nsec to reset the device.

F0i
Frame Pulse (Input).
This input accepts and automatically identifies frame
synchronization signals formatted according to different backplane specifications such
as ST-BUS and GCI.

C4i
A0-A5
Address 0 to 5 (Inputs).
These lines provide the address to MT89L85 internal
registers.
DS
Data Strobe (Input).
This is the input for the active high data strobe on the
microprocessor interface. This input operates with CS to enable the internal read and
write generation.
Clock (Input).
4.096 MHz serial clock for shifting data in and out of the data streams.
