Function
Bus Mode
– BM = static ’1’ for operation in Motorola bus
– BM = static ’0’ for operation in Intel bus mode
Address Strobe (Intel Bus Mode)
Indicates that the SEROCCO-D is driving a valid
address and bus cycle definition on pins A(23:0),
BHE (Intel mode) and R/W.
This line is tri-state when unused.
Data Strobe (8-bit Motorola bus mode only)
This active low strobe signal serves to control
read/write operations.
Bus High Enable (16-bit Intel bus mode only)
This signal indicates a data transfer on the upper
byte of the data bus (D15..D8). In 8-bit Intel bus
mode this signal has no function.
Lower Data Strobe (16-bit Motorola bus mode)
This active low strobe signal serves to control
read/write operations. Together with signal UDS
the type of bus access is determined (byte or word
access at even or odd address).
This line is tri-state when unused.
In 8-bit Intel bus mode, a pull-up resistor to V
is recommended on this pin.
Read Strobe (Intel bus mode only)
This signal indicates a read operation. The current
bus master is able to accept data on lines D(7:0) /
D(15:0) during an active RD signal.
This line is tri-state when unused.
In Motorola bus mode, a pull-up resistor to V
recommended on this pin.
