data transfers. Active low. CMOS level compatible.
Serial Port Synchronous Clock (Input). Data clock for microport. CMOS level
compatible.
Bidirectional Serial Data. Port for microprocessor serial data transfer. In
Motorola/National mode of operation, this pin becomes the data transmit pin only
and data receive is performed on the DATA 2 pin. Input CMOS level compatible.
Serial Data Receive. In Motorola/National mode of operation, this pin is used for
data receive. In Intel mode, serial data transmit and receive are performed on the
DATA 1 pin and DATA 2 is disconnected. Input CMOS level compatible.
Data Output. A high impedance three-state digital output for 8 bit wide channel
data being sent to the Layer 1 transceiver. Data is shifted out via this pin concurrent
with the rising edge of the bit clock during the timeslot defined by STB, or according
to standard ST-BUS timing.
