D0i-D3i
Ground.
2-5
Input/Microport Data Bus.
This is part of a 16 bit data bus. The data bus is bidirectional in
Connect Memory mode where it is typically interfaced to a microprocessor. In all other
modes the data bus is an input. Data to be switched through the device is clocked in at this
port.

Clock.
Master clock input which is used to clock data into and out of the device. It also clocks
the internal 11 bit counter.

Internal Connection.
Should be tied to V
SS
for normal operation.
Frame Pulse.
An active low signal that serves as a synchronous clear for the internal 11 bit
counter in all modes except Shift Register mode. The counter is cleared on a rising edge of
CK. In the Shift Register mode, FP serves to align channel boundaries.
