A3-5
Address 3-5 / Input Streams 11-13
(5V-tolerant Input). These are the inputs for the
address lines on the microprocessor interface.
22
23
DS
Data Strobe
(5V-tolerant Input). This is the input for the active high data strobe on the
microprocessor interface.
23
24
R/W
Read/Write
(5V-tolerant Input). This is the input for the read/write signal on the
microprocessor interface - high for read, low for write.
24
26
CS
Chip Select
(5V-tolerant Input). This is the input for the active low chip select on the
microprocessor interface
25-27
27-29
D7-D5
Data Bus
(5V-tolerant I/O): These are the bidirectional data pins on the microprocessor
interface.
29-33
31-35
D4-D0
Data Bus
(5V-tolerant I/O): These are the bidirectional data pins on the microprocessor
interface.

38-42
STo7-3 ST-BUS Outputs 7 to 3
(5V-Tolerant Three-state Outputs). These are the pins for the
eight 2048 kbit/s ST-BUS output streams.
41-43
44-46
STo2-0 ST-BUS Outputs 2to 0
(5V-Tolerant Three-state Outputs). These are the pins for the
eight 2048kbit/s ST-BUS output streams.
44
47
ODE
Output Drive Enable
(5V-tolerant Input). If this input is held high, the STo0-STo7 output
drivers function normally. If this input is low, the STo0-STo7 output drivers go into their
high impedance state.
NB:
Even when ODE is high, channels on the STo0-STo7
outputs can go high impedance under software control.

CSTo
Control ST-BUS Output
(5V-Tolerant Output). Each frame of 256 bits on this ST-BUS
output contains the values of bit 1 in the 256 locations of the Connection Memory High.
