Function
Read/Write Enable (Motorola bus mode)
This signal distinguishes between read and write
operation. As an input it must be valid during data
strobe (DS).
Write/Read Enable (Intel bus mode)
During master bus accesses from SEROCCO-D
(DMA) this signal indicates the transaction
direction (write/read). When SEROCCO-D is
slave, this signal is not evaluated.
This line is tri-state when unused.
If not used in Intel bus mode, a pull-up resistor to
V
Chip Select
A low signal selects SEROCCO-D for read/write
operations.
Write Strobe (Intel bus mode only)
This signal indicates a write operation. The
current bus master presents valid data on lines
D(7:0) / D(15:0) during an active WR signal.
This line is tri-state when unused.
In Motorola bus mode, a pull-up resistor to V
recommended on this pin.
Width Of Bus Interface
A low signal on this input selects the 8-bit bus
interface mode.
A high signal on this input selects the 16-bit bus
interface mode. In this case word transfer to/from
the internal registers is enabled. Byte transfers
are implemented by using BLE and BHE (Intel bus
mode) or LDS and UDS (Motorola bus mode)
Clock
The system clock for SEROCCO-D is provided
through this pin.
DD3
is recommended on this pin.
